Description
CATO supplies Lincomycin EP Impurity D(Clindamycin EP Impurity D) (CAS 17017-22-0), a pharmacopoeial impurity reference standard (molecular formula C18H34N2O6S, MW 406.54 g/mol) used for the identification and quantification of trace impurities in APIs.
Lincomycin EP Impurity D(Clindamycin EP Impurity D) (C18H34N2O6S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
As a certified reference material (CRM), Lincomycin EP Impurity D(Clindamycin EP Impurity D) 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.
