Chemical Structure

Maxacalcitol Impurity 24 CAS CATO-C4X-278824 chemical structure

Description

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 supplies Maxacalcitol Impurity 24 (CAS CATO-C4X-278824), a pharmacopoeial impurity reference standard (molecular formula C12H22O2, MW 198.30 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Maxacalcitol Impurity 24 (C12H22O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 198.30 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
