Description

Norchlorpromazine CAS NO 1225-64-5 is a high-purity pharmaceutical intermediate and research chemical, a chlorinated derivative of the phenothiazine class. This compound is valued for its role as a key precursor in the synthesis of advanced active pharmaceutical ingredients (APIs) and for specialized chemical research. It is primarily required by pharmaceutical manufacturers, R&D laboratories, and fine chemical synthesis facilities engaged in developing and producing neuroleptic agents and other complex organic molecules.

Application

• Pharmaceutical Intermediate: A critical building block in the synthesis of phenothiazine-derived antipsychotic and antiemetic drugs.
• Chemical Research & Development: Used in academic and industrial R&D for studying structure-activity relationships (SAR) and developing new therapeutic agents.
• Reference Standard: Serves as a certified reference material (CRM) for analytical method development, validation, and quality control in pharmaceutical analysis.
• Fine Chemical Synthesis: Employed in multi-step organic synthesis to create novel chemical entities with potential biological activity.
