Phenylperi acid

Phenylperi acid (CAS 82-76-8 ), commercially abbreviated as 1,8-ANS, is an aminonaphthalenesulfonic acid derivative used as a UV stabilizer and antioxidant in industrial formulations. It functions by absorbing ultraviolet radiation and inhibiting oxidative degradation. This chemical intermediate is essential for extending the service life of finished materials. In coatings and adhesives, it is incorporated to protect substrates from UV-induced yellowing and mechanical property loss over time. Textile and leather processors use it as a dye intermediate and stabilizer, where it contributes to colorfastness and resistance to light-induced fading. It is a versatile component in many specialty chemical processes. Polymer compounders add it to plastics formulations requiring long-term UV stability, particularly in outdoor or high-exposure applications. This ensures that structural integrity is maintained even under harsh environmental conditions. In printing inks and packaging materials, it supports pigment stability and prevents premature degradation of colorants under light exposure. This makes it a valuable additive for the commercial printing and labeling industries. Phenylperi acid is supplied as a crystalline powder, typically in technical grade. Standard packaging includes drum and bag formats suited to industrial procurement volumes for large-scale manufacturing operations. Buyers should confirm purity specifications and batch consistency directly with the supplier, as grade designations vary by manufacturer. Proper storage and handling are required to maintain the chemical stability of the product. Contact us for supply of Phenylperi acid Request Quote
