Amido Black 10B, systematically cataloged under the Color Index designation as Acid Black 1 (C.I. 20470), is a complex disazo dyestuff. Highly regarded for its exceptional protein-binding affinity and intense deep-blue to black coloration, this chemical compound plays an irreplaceable role in both the scientific research laboratory and heavy industry. At Tianjin Sunrise Chem Group, we refine its synthesis to guarantee a high-purity product tailored for advanced applications.
Chemically structured as Sodium 4-amino-5-hydroxy-3-[(4-nitrophenyl)diazenyl]-6-(phenyldiazenyl)naphthalene-2,7-disulfonate, with a molecular formula of C22H14N6Na2O9S2, Amido Black 10B is highly soluble in water and organic solvents like acetic acid and methanol. This multi-functional solubility allows chemists and forensic scientists to formulate staining reagents with distinct evaporation rates and absorption properties.
Our raw material purification methods prevent the crystallization of inorganic salts and excess intermediates (such as p-nitroaniline or H-acid). This translates directly into highly stable batches with minimal trace metal contamination, ensuring that whether used as an analytical reagent in polyacrylamide gel electrophoresis (PAGE) or as a bulk textile dye, the performance remains completely predictable.
From molecular biology to criminal investigations and high-performance manufacturing, Acid Black 1 serves as an essential functional component across diverse sectors.
Amido Black 10B selectively binds to blood proteins, enabling the physical visualization of faint or hidden bloody footprints, fingerprint ridges, and biological evidence on both porous and non-porous surfaces. It is a standard chemical solution employed by global police agencies and law enforcement laboratories.
In biotechnology, Amido Black is widely utilized for staining proteins transferred onto nitrocellulose, PVDF, or nylon membranes. Offering clear sensitivity with low background staining, it enables researchers to visualize protein bands post-transfer without interfering with subsequent mass spectrometry analysis.
As an acid dye, Acid Black 1 demonstrates exceptional affinity for natural protein fibers (wool and silk) as well as polyamide fibers (nylon). It delivers deep black shades characterized by high lightfastness, excellent leveling performance, and reliable washfastness in acidic dye baths.
Amido Black's intense light absorption properties make it ideal for formulating industrial inkjet inks, office supply markers, and stamping pads. It ensures stable dispersion in water-glycol solvent matrices without clogging high-precision nozzles or bleeding excessively into paper.
Tianjin Sunrise Chem Group specializes in manufacturing high-quality dyestuffs. Our chemical division includes Direct dyes, Acid dyes, Basic dyes, Sulphur dyes, Solvent dyes, Liquid dyes, and Fluorescent dyes. Backed by decades of industry and export experience, we have built a solid reputation for reliability and excellence, serving clients from diverse sectors including denim, textile, leather, paper, and plastic.
We highly focus on product quality and batch stability. Each batch undergoes rigorous laboratory testing before dispatch to the shipping port. Our ZDHC Level 3 and GOTS certifications guarantee international standard environmental compliance. We work closely with chemical buyers, providing customized color blending and tailor-made logistics solutions. Collaborative growth, mutual trust, and green innovation form the foundation of our operation.
In an era of regulatory shifts and supply volatility, Sunrise Chem ensures a stable flow of Acid Black 1 to major industrial centers around the world.
The global demand for Amido Black 10B is driven by expanding biotechnology research in North America and Western Europe, combined with the growth of high-grade leather and textile manufacturing in Asia-Pacific. However, procurement managers often struggle with batch-to-batch variation and strict environmental audits.
Tianjin Sunrise Chem Group addresses these challenges through raw material backward integration and optimized synthesis pathways. Cooperating with textile and paper mills for many years demonstrates that our factory has established a strong and reliable business relationship. This kind of long-term collaboration brings numerous benefits, such as consistent orders, shared resources, and mutual support. It indicates that the factory has a good track record of delivering quality products and meeting the needs of its partners. Our mission is to drive business growth by providing reliable and customized products. We aim to contribute significantly to our customers' success by delivering first-class products and exceptional customer service.
Environmental protection is the cornerstone of our innovation. We dedicate ourselves to providing eco-friendly, high-performance colorants that balance productivity with environmental harmony.
The ZDHC (Zero Discharge of Hazardous Chemicals) program is a collaborative effort by leading brands, retailers, and suppliers in the textile and footwear industry to reduce the use of hazardous chemicals. Achieving ZDHC Level 3 certification indicates that our chemical products, manufacturing pathways, and management procedures meet the highest criteria for safety, chemical handling, wastewater treatment, and pollution prevention, eliminating harmful effluents throughout the supply chain.
The GOTS certification ensures the organic status of textiles from the harvesting of raw materials through environmentally and socially responsible manufacturing. The certification guarantees that our dyestuff inputs minimize toxic substances, respect strict ecological parameters, and adhere to social labor standards. Choosing GOTS-certified dyes ensures your finished consumer products are sustainable, safe, and ethical.
Both certifications are critical in the context of sustainable and responsible textile production. ZDHC focuses on the absolute elimination of hazardous chemicals, while GOTS guarantees organic and ethical compliance. We invite you to choose us as your trusted partner in achieving green supply goals.
We align our industrial dye supplies with your local logistical capabilities and safety frameworks to eliminate operational friction.
Whether operating a high-volume textile dyeing facility in Southeast Asia, a forensic laboratory in Western Europe, or a paper mill in Latin America, local requirements dictate your chemistry choices. We provide tailored SDS (Safety Data Sheets) in multiple languages and supply options of varying concentrations—ranging from crude industrial powders to salt-free desalinated granules and liquid solutions.
We have successfully established strong partnerships in many countries. Our dedication to meeting global demands and exceeding customer expectations has earned us a reputation as a reliable supplier worldwide. Our logistics network facilitates safe sea freight, door-to-door customs clearance, and containerized transport systems to protect the chemical integrity of every dye shipment.
Our research and development initiatives focus on green chemistry, circular economy integration, and ultra-high purity synthesis.
By optimizing the diazotization process of H-acid and p-nitroaniline, we minimize trace impurities. This research target aligns with increasingly stringent EU REACH standards regarding primary aromatic amines (PAAs).
Our laboratory is refining the membrane filtration (reverse osmosis) of Amido Black to produce salt-free versions. Eliminating inorganic sodium chloride and sulfate reduces TDS in industrial dyeing wastewater and increases solubility in liquid ink concentrates.
We are scaling carbon-neutral production lines, utilizing solar-heated reactors and biological wastewater filters to treat effluents. This ensures our factory remains a sustainable source of dyes for the global market.
