Chemical Structure

Bevantolol Impurity 10 CAS 54738-15-7 chemical structure

Description

As a certified reference material (CRM), Bevantolol 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.

Bevantolol Impurity 10 (CAS 54738-15-7) is a certified pharmaceutical impurity reference standard with the molecular formula C19H25NO4 and a molecular weight of 331.41 g/mol.

Bevantolol Impurity 10 (C19H25NO4) 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.
