Chemical Structure

Suvorexant Impurity 38 CAS CATO-C4X-181238 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 329.41 g/mol gives Suvorexant Impurity 38 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Suvorexant Impurity 38 (CAS CATO-C4X-181238), a pharmacopoeial impurity reference standard (molecular formula C15H23NO5S, MW 329.41 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Suvorexant Impurity 38 (C15H23NO5S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. 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 329.41 g/mol, it falls into the moderately-high-molecular-weight range. 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), Suvorexant Impurity 38 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.
