Description
CATO manufactures 2-(3-Aminophenyl)-6,8-dimethylquinoline-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.
2-(3-Aminophenyl)-6,8-dimethylquinoline-4-carboxylic acid (CAS 590359-90-3) is a high-purity analytical reference standard with the molecular formula C18H16N2O2 and a molecular weight of 292.33 g/mol.
The molecular framework of 2-(3-Aminophenyl)-6,8-dimethylquinoline-4-carboxylic acid (C18H16N2O2) 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).
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.
