Chemical Structure

Olmesartan Impurity 63 CAS 144690-06-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 177.20 g/mol gives Olmesartan Impurity 63 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Olmesartan Impurity 63 (CAS 144690-06-2), a pharmacopoeial impurity reference standard (molecular formula C9H11N3O, MW 177.20 g/mol) used for the identification and quantification of trace impurities in APIs.

Olmesartan Impurity 63 (C9H11N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), Olmesartan Impurity 63 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.
