6,8-Dimethyl-2-(m-tolyl)quinoline-4-carboxylic acid CAS 438228-13-8

Description

The occurrence of 6,8-Dimethyl-2-(m-tolyl)quinoline-4-carboxylic acid is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6,8-Dimethyl-2-(m-tolyl)quinoline-4-carboxylic acid (CAS 438228-13-8) is a high-purity analytical reference standard with the molecular formula C19H17NO2 and a molecular weight of 291.34 g/mol.

The molecular framework of 6,8-Dimethyl-2-(m-tolyl)quinoline-4-carboxylic acid (C19H17NO2) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures 6,8-Dimethyl-2-(m-tolyl)quinoline-4-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.
