Chemical Structure

Levocarnitine Impurity 7 CAS CATO-C4X-12927 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 Levocarnitine Impurity 7 (CAS CATO-C4X-12927), a pharmacopoeial impurity reference standard (molecular formula C7H15NO5S, MW 225.26 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Levocarnitine Impurity 7 (C7H15NO5S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 225.26 g/mol, it falls into the medium-molecular-weight range. 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.
