Clindamycin Impurity 61 CAS 22965-79-3

Description

Compared with other compounds in its class, the molecular weight of 271.76 g/mol gives Clindamycin Impurity 61 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Clindamycin Impurity 61 (CAS 22965-79-3), a pharmacopoeial impurity reference standard (molecular formula C9H18ClNO4S, MW 271.76 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C9H18ClNO4S, Clindamycin Impurity 61 contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 271.76 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), Clindamycin Impurity 61 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.
