Esomeprazole Impurity 116 CAS 109371-19-9

Description

Compared with other compounds in its class, the molecular weight of 151.21 g/mol gives Esomeprazole Impurity 116 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Esomeprazole Impurity 116 (CAS 109371-19-9), a pharmacopoeial impurity reference standard (molecular formula C9H13NO, MW 151.21 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Esomeprazole Impurity 116 (C9H13NO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 151.21 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), Esomeprazole Impurity 116 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.
