Chemical Structure
Description
The occurrence of Tebipenem Impurity 9 is closely related to a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Tebipenem Impurity 9 (CAS 19975-56-5), a pharmacopoeial impurity reference standard (molecular formula C4H7NS2, MW 133.24 g/mol) used for the identification and quantification of trace impurities in APIs.
Tebipenem Impurity 9 (C4H7NS2) contains a nitrile group, sulfur-containing functionality. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
CATO manufactures Tebipenem Impurity 9 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
