Understanding 2,5-Diaminobenzenesulfonic Acid: A Key Dye Intermediate
In the dynamic world of chemical manufacturing, understanding the properties and applications of key intermediates is paramount for procurement and R&D professionals. 2,5-Diaminobenzenesulfonic acid, identified by CAS number 88-45-9, stands out as a critical component in the synthesis of a wide array of dyes, particularly within the textile industry. This article aims to provide B2B buyers with a comprehensive understanding of this versatile compound, highlighting its importance, quality considerations, and the advantages of sourcing it from established manufacturers.
What is 2,5-Diaminobenzenesulfonic Acid?
2,5-Diaminobenzenesulfonic acid is an aromatic sulfonic acid characterized by two amino groups and one sulfonic acid group attached to a benzene ring. Its chemical formula is C6H8N2O3S, with a molecular weight of 188.20. It is typically supplied as a violet powder, with a high purity assay of 98%min. This specific structure makes it an ideal building block for creating complex dye molecules, influencing their color, solubility, and binding properties to various substrates.
Key Applications in the Dye Industry
The primary utility of 2,5-diaminobenzenesulfonic acid lies in its role as a precursor for synthesizing various dyes. It is particularly crucial for the production of:
- Direct Blue 176 (C.I. 35460): A widely used dye for cotton and other cellulosic fibers, known for its good lightfastness and washfastness.
- Direct Black 32 (C.I. 35440): A common black dye for textiles, providing deep shades and good all-around performance.
- Black Blue G (C.I. 35450): Another important colorant in the textile industry.
Beyond these specific dyes, it also finds application in more specialized areas, such as laccase-mediated dyeing of cotton, which is an emerging area in sustainable textile processing. For those looking to buy 2,5-diaminobenzenesulfonic acid for these applications, understanding its role as a reliable chemical intermediate is key.
Quality and Sourcing Considerations for B2B Buyers
When sourcing chemical intermediates, especially for large-scale industrial production, consistency in quality and purity is non-negotiable. A minimum assay of 98% for 2,5-diaminobenzenesulfonic acid is standard, ensuring that the compound will perform as expected in complex synthesis reactions. Procurement managers and R&D scientists often search for 2,5-diaminobenzenesulfonic acid manufacturer China or CAS 88-45-9 dye precursor price to identify reliable suppliers. Choosing a reputable manufacturer in China can offer significant advantages in terms of both cost-effectiveness and availability.
