Description
CATO supplies Pirarubicin Impurity 3 (CAS CATO-C4X-24683), a pharmacopoeial impurity reference standard (molecular formula C31H35NO12, MW 613.61 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Pirarubicin Impurity 3 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 613.61 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 Pirarubicin Impurity 3 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.
