Chemical Structure

Perindopril Impurity N2 t-Butylamine CAS 82978-68-5 chemical structure

Description

The occurrence of Perindopril Impurity N2 t-Butylamine is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Perindopril Impurity N2 t-Butylamine (CAS 82978-68-5) is a certified pharmaceutical impurity reference standard with the molecular formula C19H32N2O5C4H11N and a molecular weight of 441.61 g/mol.

The molecular framework of Perindopril Impurity N2 t-Butylamine (C19H32N2O5C4H11N) is characterized by a steroid 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).

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

As a certified reference material (CRM), Perindopril Impurity N2 t-Butylamine 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.
