Chemical Structure
Description
2,3-dimethyl-6-(4-methylphenoxy)quinolin-4(1H)-one (CAS 1178722-67-2) is a high-purity analytical reference standard with the molecular formula C18H17NO2 and a molecular weight of 279.33 g/mol.
The molecular framework of 2,3-dimethyl-6-(4-methylphenoxy)quinolin-4(1H)-one (C18H17NO2) 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 2,3-dimethyl-6-(4-methylphenoxy)quinolin-4(1H)-one 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.
