Lincomycin sulfone Impurity CAS 198080-68-1

Description

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

CATO supplies Lincomycin sulfone Impurity (CAS 198080-68-1), a pharmacopoeial impurity reference standard (molecular formula C18H34N2O8S, MW 438.54 g/mol) used for the identification and quantification of trace impurities in APIs.

The molecular framework of Lincomycin sulfone Impurity (C18H34N2O8S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
