N-Phenyl-p-phenylenediamine sulfate (Gray BS) is a specialized oxidative coupling intermediate primarily synthesized via the sulfation of N-phenyl-p-phenylenediamine. This chemical intermediate serves as a critical precursor in dye manufacturing, particularly for developing stable gray and black pigments. Its molecular formula is C12H14N2O4S, with the CAS number 8005-97-6.
This substance requires storage in a cool, dry, and well-ventilated area away from oxidizers. Personnel must wear appropriate PPE including gloves and respiratory protection due to potential skin sensitization and toxicity risks upon exposure.
