Products Description of Direct Pigment Yellow 3 CAS#6486-23-3
Pigment Yellow 3 (CAS# 6486-23-3) is a high-performance monoazo yellow pigment supplied as a finely dispersed greenish-yellow powder. Highly valued for its chemical resilience, it exhibits negligible color change when exposed to concentrated nitric acid, concentrated hydrochloric acid, or dilute sodium hydroxide, while shifting yellow in concentrated sulfuric acid. It dissolves in warm organic solvents such as ethanol and acetone. (Note: Intended primarily for industrial, technical, and scientific research applications; not for medical or diagnostic use.)
