Chemical Structure
Description
CATO supplies N-(3,4-Dimethylphenyl)-1-oxo-1H-isochromene-3-carboxamide (CAS 354999-94-3), a certified reference material (molecular formula C18H15NO3, MW 293.32 g/mol) for analytical method development and quality control.
The molecular framework of N-(3,4-Dimethylphenyl)-1-oxo-1H-isochromene-3-carboxamide (C18H15NO3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures N-(3,4-Dimethylphenyl)-1-oxo-1H-isochromene-3-carboxamide 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.
