Chemical Structure

Irbesartan Impurity 10 CAS 1312996-19-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 388.42 g/mol gives Irbesartan Impurity 10 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Irbesartan Impurity 10 (CAS 1312996-19-2) is a certified pharmaceutical impurity reference standard with the molecular formula C21H20N6O2 and a molecular weight of 388.42 g/mol.

Based on its molecular formula C21H20N6O2, Irbesartan Impurity 10 contains a steroid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 388.42 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), Irbesartan Impurity 10 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.
