Pentoxyverine Impurity 6 CAS CATO-C4X-22706

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Pentoxyverine Impurity 6.

CATO supplies Pentoxyverine Impurity 6 (CAS CATO-C4X-22706), a pharmacopoeial impurity reference standard (molecular formula C15H20O2, MW 232.32 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Pentoxyverine Impurity 6 (C15H20O2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 232.32 g/mol, it falls into the medium-molecular-weight range. 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.

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.
