Chemical Structure

Clindamycin Phosphate Sulfoxide Impurity CAS 1228573-90-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 520.96 g/mol gives Clindamycin Phosphate Sulfoxide Impurity distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Clindamycin Phosphate Sulfoxide Impurity (CAS 1228573-90-7), a pharmacopoeial impurity reference standard (molecular formula C18H34ClN2O9PS, MW 520.96 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an amide group, a sulfone group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, Clindamycin Phosphate Sulfoxide Impurity is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 520.96 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures Clindamycin Phosphate Sulfoxide Impurity under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
