Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 448.39 g/mol gives Aripiprazole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Aripiprazole (CAS 129722-12-9), molecular formula C23H27Cl2N3O2 and molecular weight 448.39 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, Aripiprazole (C23H27Cl2N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 11.0, corresponding to approximately 11 ring(s) or double-bond equivalent(s). With a molecular weight of 448.39 g/mol, it falls into the moderately-high-molecular-weight range. 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
As a certified reference material (CRM), Aripiprazole 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.
