In the dynamic world of chemical manufacturing, certain compounds stand out for their pivotal role in creating essential products. One such compound is Phenyl J Acid, identified by its CAS number 119-40-4. This critical dye intermediate is indispensable for producing a wide spectrum of vibrant and durable colors, particularly within the azo dye family. For procurement managers and R&D scientists seeking high-quality chemical raw materials, understanding the significance and sourcing of Phenyl J Acid is paramount.

Phenyl J Acid, chemically known as 7-Anilino-4-hydroxy-2-naphthalenesulfonic acid, serves as a fundamental building block for numerous dyes. Its unique molecular structure allows it to be readily involved in diazotization and coupling reactions, the core processes for creating azo dyes. These dyes are widely used across various industries, including textiles, leather, paper, and inks, due to their excellent color yield, variety of shades, and generally good fastness properties. When you need to buy Phenyl J Acid, seeking a reliable manufacturer that guarantees high purity, such as 99.5% minimum assay, is crucial for ensuring the consistent quality of your final dye products.

The applications of Phenyl J Acid are diverse. It is particularly noted for its use in synthesizing specific dyes like Light Fast Blue RGL, renowned for its superior lightfastness. Furthermore, it is a key component in the production of copper salt dyes, including copper salt green BTL, copper salt blue FBGL, and copper salt purple BBL. These specialized dyes offer specific chromatic and fastness characteristics demanded by niche markets. For businesses looking to purchase these types of dyes, securing a stable supply of high-grade Phenyl J Acid from a trusted supplier in China is a strategic advantage.

When evaluating Phenyl J Acid price and availability, it's essential to consider the expertise of the manufacturer. A reputable chemical supplier will not only offer competitive pricing but also provide comprehensive product specifications, safety data sheets (SDS), and technical support. For instance, understanding the typical appearance, such as a blue or blue-gray powder, and the packaging options, like 25kg drums, aids in logistical planning. If you are looking to procure Phenyl J Acid for your production needs, exploring options from established manufacturers will ensure you receive a product that meets your exact requirements.

For R&D scientists and formulators, the purity of chemical intermediates directly impacts the performance of the final product. The 99.5% minimum assay commonly offered for Phenyl J Acid ensures minimal impurities, leading to more predictable reaction outcomes and superior dye performance. This level of quality is a hallmark of diligent manufacturing processes. We encourage you to connect with leading Phenyl J Acid suppliers who prioritize quality control and offer reliable service to meet your ongoing chemical sourcing needs.
