Chemical Structure

Valsartan Impurity 100 CAS CATO-C4X-1057100 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 335.40 g/mol gives Valsartan Impurity 100 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Valsartan Impurity 100 (CAS CATO-C4X-1057100), a pharmacopoeial impurity reference standard (molecular formula C19H21N5O, MW 335.40 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Valsartan Impurity 100 (C19H21N5O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 335.40 g/mol, it falls into the moderately-high-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), Valsartan Impurity 100 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.
