Aprepitant Impurity 80 CAS CATO-C4X-114180

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Aprepitant Impurity 80.

Aprepitant Impurity 80 (CAS CATO-C4X-114180) is a certified pharmaceutical impurity reference standard with the molecular formula C9H13O4P and a molecular weight of 216.17 g/mol.

Based on its molecular formula C9H13O4P, Aprepitant Impurity 80 contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 216.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Aprepitant Impurity 80 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.
