In the rigorous and highly regulated world of Active Pharmaceutical Ingredient (API) manufacturing, the selection and procurement of high-quality intermediates are critical for success. Among these vital components, 4-Hydrazinobenzenesulfonamide (CAS 4392-54-5) holds a prominent position, particularly due to its indispensable role in the synthesis of Celecoxib. This article explores its significance for API manufacturers and provides insights into sourcing strategies.
4-Hydrazinobenzenesulfonamide: A Lynchpin in Celecoxib Synthesis
The primary function of 4-Hydrazinobenzenesulfonamide in API manufacturing is as a foundational intermediate for Celecoxib. Celecoxib, a well-established nonsteroidal anti-inflammatory drug (NSAID), is synthesized through a multi-step process where 4-Hydrazinobenzenesulfonamide serves as a key building block. Its specific chemical structure enables crucial reactions that lead to the formation of the Celecoxib molecule. For API manufacturers, sourcing this intermediate with guaranteed purity (typically ≥98.0%) is non-negotiable to ensure the efficacy, safety, and regulatory compliance of the final drug product.
Properties and Specifications for Manufacturers
API manufacturers must pay close attention to the detailed specifications of 4-Hydrazinobenzenesulfonamide. The typical physical form is an off-white to light beige powder, which is convenient for industrial handling. Key properties such as melting point (158-159°C) and assay (≥98.0%) are thoroughly vetted. The molecular formula C6H9N3O2S and molecular weight of 187.22 g/mol are also fundamental identifiers. When looking to purchase this chemical, understanding these specifications ensures you are acquiring material suitable for pharmaceutical-grade synthesis.
