Chemical Structure

Ibuprofen Impurity 84 CAS CATO-C4X-108284 chemical structure

Description

The occurrence of Ibuprofen Impurity 84 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 Ibuprofen Impurity 84 (CAS CATO-C4X-108284), a pharmacopoeial impurity reference standard (molecular formula C21H25NO3, MW 339.43 g/mol) used for the identification and quantification of trace impurities in APIs.

Ibuprofen Impurity 84 (C21H25NO3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Ibuprofen Impurity 84 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.
