SAR107375E Impurity 7 CAS 5877-96-3 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including SAR107375E Impurity 7.

CATO supplies SAR107375E Impurity 7 (CAS 5877-96-3), a pharmacopoeial impurity reference standard (molecular formula C8H10O3S, MW 186.23 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C8H10O3S, SAR107375E Impurity 7 contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 186.23 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), SAR107375E Impurity 7 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.
