Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Sulbactam Impurity 31.
CATO supplies Sulbactam Impurity 31 (CAS CATO-C4X-175631), a pharmacopoeial impurity reference standard (molecular formula C8H12N2O7S, MW 280.26 g/mol) used for the identification and quantification of trace impurities in APIs.
Sulbactam Impurity 31 (C8H12N2O7S) contains a carbohydrate-derived structure, an amide group, a sulfone group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
CATO manufactures Sulbactam Impurity 31 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.
