Nimodipine Impurity 31 CAS 62044-14-8 chemical structure

Description

Nimodipine Impurity 31 (CAS 62044-14-8) is a certified pharmaceutical impurity reference standard with the molecular formula C15H17NO7 and a molecular weight of 323.30 g/mol.

Nimodipine Impurity 31 (C15H17NO7) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Nimodipine Impurity 31 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.
