Chemical Structure
Description
2-(2,4-Dimethylphenyl)-4-oxo-1,4-dihydroquinoline-8-carboxylic acid (CAS 90034-78-9) is a high-purity analytical reference standard with the molecular formula C18H15NO3 and a molecular weight of 293.32 g/mol.
The molecular framework of 2-(2,4-Dimethylphenyl)-4-oxo-1,4-dihydroquinoline-8-carboxylic acid (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 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-(2,4-Dimethylphenyl)-4-oxo-1,4-dihydroquinoline-8-carboxylic acid 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.
