Chemical Structure

Carboprost Impurity 11 CAS CATO-C4X-210311 chemical structure

Description

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.

CATO supplies Carboprost Impurity 11 (CAS CATO-C4X-210311), a pharmacopoeial impurity reference standard (molecular formula C22H36O4, MW 364.52 g/mol) used for the identification and quantification of trace impurities in APIs.

Carboprost Impurity 11 (C22H36O4) contains a steroid core, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
