Description
CATO supplies Glipizide EP Impurity C (CAS 13554-93-3), a pharmacopoeial impurity reference standard (molecular formula C18H27N3O5S, MW 397.49 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Glipizide EP Impurity C is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 397.49 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.
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 Glipizide EP Impurity C 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.
