Chemical Structure

Nifedipine Impurity 41 CAS 80012-11-9 chemical structure

Description

The occurrence of Nifedipine Impurity 41 is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Nifedipine Impurity 41 (CAS 80012-11-9), a pharmacopoeial impurity reference standard (molecular formula C5H9NO2, MW 115.13 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Nifedipine Impurity 41 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 115.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

CATO manufactures Nifedipine Impurity 41 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.
