Chemical Structure

Etodolac EP Impurity H CAS 41340-36-7 chemical structure

Description

Based on its molecular formula C12H15NO, Etodolac EP Impurity H contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 189.25 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).

As a process- or degradation-related impurity, Etodolac EP Impurity H (CAS 41340-36-7, C12H15NO) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

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 Etodolac EP Impurity H 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.
