Linezolid Impurity 77 CAS 183905-31-9

Description

Compared with other compounds in its class, the molecular weight of 193.63 g/mol gives Linezolid Impurity 77 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Linezolid Impurity 77 (CAS 183905-31-9), a pharmacopoeial impurity reference standard (molecular formula C7H12ClNO3, MW 193.63 g/mol) used for the identification and quantification of trace impurities in APIs.

Linezolid Impurity 77 (C7H12ClNO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.

As a certified reference material (CRM), Linezolid Impurity 77 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
