For procurement managers in the chemical and textile industries, sourcing critical intermediates like 2-Amino-5-hydroxynaphthalene-1,7-disulfonic acid (CAS 6535-70-2) is paramount to ensuring product quality and production continuity. This compound, often referred to by its CAS number, is a cornerstone in the synthesis of various dyes and pigments, particularly in the realm of acid and reactive dyes. Understanding where to buy and what to look for from a reputable dye intermediate manufacturer is key to a successful procurement strategy.

When searching for a reliable supplier of 2-Amino-5-hydroxynaphthalene-1,7-disulfonic acid, particularly those based in China, several factors come into play. Firstly, consistency in product specifications, such as a minimum assay of 70% and a clean appearance (typically a gray powder), is non-negotiable. This ensures that the intermediate will perform as expected in complex synthesis reactions, leading to vibrant and stable end products. Buyers should always request Certificates of Analysis (CoA) to verify purity and chemical composition before placing an order.

The molecular formula, C10H9NO7S2, and a molecular weight of 319.31, define the chemical's identity. However, its true value lies in its functional groups—amino, hydroxyl, and two sulfonic acid moieties—which are crucial for its role as a coupling component in azo dye formation. These functional groups facilitate the creation of chromophores, the parts of a molecule responsible for its color. Therefore, understanding the specific application, such as in synthesis of acid dyes or pigments for textiles and paper, is vital for selecting the right grade and supplier.

Procurement managers often inquire about the price of CAS 6535-70-2. While prices can fluctuate based on market demand, production costs, and order volume, it is essential to establish relationships with manufacturers who can offer competitive pricing without compromising on quality. Direct sourcing from established chemical manufacturers in China can often provide significant cost advantages. NINGBO INNO PHARMCHEM CO.,LTD. is committed to offering high-quality intermediates at competitive rates, ensuring that our clients receive excellent value.

Furthermore, storage and packaging are critical considerations. Typically, 2-Amino-5-hydroxynaphthalene-1,7-disulfonic acid should be stored in a dry, cool, well-ventilated place, sealed and shaded from light, to maintain its stability and shelf life. Packaging commonly involves 25kg or 50kg bags, but customized packaging solutions can also be arranged. When you buy 2-Amino-5-hydroxynaphthalene-1,7-disulfonic acid from a trusted partner, you gain peace of mind regarding product integrity from manufacturing to delivery.

In conclusion, selecting the right chemical intermediate supplier is a strategic decision. By focusing on purity, consistent supply, competitive pricing, and reliable technical support, procurement professionals can ensure the success of their dye and pigment manufacturing operations.
