Ketorolac Impurity 52 CAS 147088-89-9

Description

The occurrence of Ketorolac Impurity 52 is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Ketorolac Impurity 52 (CAS 147088-89-9), a pharmacopoeial impurity reference standard (molecular formula C18H13NO2, MW 275.30 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C18H13NO2, Ketorolac Impurity 52 contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 275.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), Ketorolac Impurity 52 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
