Chemical Structure
Description
CATO manufactures Ketorolac Impurity 72 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.
CATO supplies Ketorolac Impurity 72 (CAS CATO-C4X-166972), a pharmacopoeial impurity reference standard (molecular formula C11H15BO5, MW 238.04 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Ketorolac Impurity 72 (C11H15BO5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.5, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 238.04 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
