Phenothiazine

Phenothiazine (CAS 92-84-2), also known as PTZ, is an organosulfur heterocyclic compound used industrially as an antioxidant, polymerization inhibitor, and biocide.

Where is Phenothiazine used?

• Polymer and plastics production: monomer stabilizer
• Inhibits runaway polymerization of vinyl and acrylic monomers during storage and transport
• Rubber compounding: antioxidant extending service life of tire and industrial rubber goods
• Lubricant and metalworking fluid formulations: controls oxidative breakdown at elevated temperatures, reducing deposit formation
• Agricultural and veterinary: anthelmintic active and component in formulations targeting parasitic infections in livestock
• It prevents premature crosslinking, oxidative degradation, and microbial activity in chemical processes and formulated products.

Commercial specifications

• Purity specifications typically range from 98% to 99%+
• Documentation including COA and MSDS as standard for bulk procurement
