Chemical Structure

Brexpiprazole Impurity 48 CAS 2059942-13-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 466.96 g/mol gives Brexpiprazole Impurity 48 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Brexpiprazole Impurity 48 (CAS 2059942-13-9) is a certified pharmaceutical impurity reference standard with the molecular formula C26H27ClN2O4 and a molecular weight of 466.96 g/mol.

Structurally, Brexpiprazole Impurity 48 (C26H27ClN2O4) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 466.96 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).

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.

CATO manufactures Brexpiprazole Impurity 48 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
