Chemical Structure

Pranoprofen Impurity 36 CAS 261-27-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Pranoprofen Impurity 36.

CATO supplies Pranoprofen Impurity 36 (CAS 261-27-8), a pharmacopoeial impurity reference standard (molecular formula C12H9NO, MW 183.21 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C12H9NO, Pranoprofen Impurity 36 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 183.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 Pranoprofen Impurity 36 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.
