Sulindac Impurity 89 CAS 37794-15-3

Description

Compared with other compounds in its class, the molecular weight of 168.21 g/mol gives Sulindac Impurity 89 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Sulindac Impurity 89 (CAS 37794-15-3), a pharmacopoeial impurity reference standard (molecular formula C8H8O2S, MW 168.21 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Sulindac Impurity 89 (C8H8O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 168.21 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), Sulindac Impurity 89 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.
