Eletriptan Impurity 1 CAS 6163-58-2 chemical structure

Description

As a certified reference material (CRM), Eletriptan Impurity 1 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.

Eletriptan Impurity 1 (CAS 6163-58-2) is a certified pharmaceutical impurity reference standard with the molecular formula C21H21P and a molecular weight of 304.37 g/mol.

Owing to organophosphorus functionality, a polycyclic aromatic system, Eletriptan Impurity 1 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
