Chemical Structure

Brexpiprazole Impurity 13 CAS 15116-41-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 253.30 g/mol gives Brexpiprazole Impurity 13 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Brexpiprazole Impurity 13 (CAS 15116-41-3) is a certified pharmaceutical impurity reference standard with the molecular formula C16H15NO2 and a molecular weight of 253.30 g/mol.

Brexpiprazole Impurity 13 (C16H15NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Brexpiprazole Impurity 13 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.
