Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 293.40 g/mol gives Perospirone Impurity 45 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Perospirone Impurity 45 (CAS 1253785-79-3) is a certified pharmaceutical impurity reference standard with the molecular formula C16H27N3O2 and a molecular weight of 293.40 g/mol.
Perospirone Impurity 45 (C16H27N3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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), Perospirone Impurity 45 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.
