Chemical Structure

Drotaverin Impurity 48 CAS 1536475-50-9 chemical structure

Description

The occurrence of Drotaverin Impurity 48 is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Drotaverin Impurity 48 (CAS 1536475-50-9) is a certified pharmaceutical impurity reference standard with the molecular formula C22H29NO5 and a molecular weight of 387.47 g/mol.

The molecular framework of Drotaverin Impurity 48 (C22H29NO5) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), Drotaverin Impurity 48 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.
