Chemical Structure
Description
As a process- or degradation-related impurity, Aztreonam Impurity 51 (CAS CATO-C4X-152251, C19H31N7O10S2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Aztreonam Impurity 51 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 581.62 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 Aztreonam Impurity 51 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.
