Brexpiprazole impurity 113 CAS 2126178-13-8

Description

As a certified reference material (CRM), Brexpiprazole impurity 113 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.

CATO supplies Brexpiprazole impurity 113 (CAS 2126178-13-8), a pharmacopoeial impurity reference standard (molecular formula C20H18N2S2, MW 350.50 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Brexpiprazole impurity 113 (C20H18N2S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 350.50 g/mol, it falls into the moderately-high-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
