Lercanidipine Impurity 27 CAS 2250243-16-2

Description

The occurrence of Lercanidipine Impurity 27 is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Lercanidipine Impurity 27 (CAS 2250243-16-2) is a certified pharmaceutical impurity reference standard with the molecular formula C20H25N and a molecular weight of 279.42 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, Lercanidipine Impurity 27 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 279.42 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), Lercanidipine Impurity 27 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.
