2,3-Dimethylquinoline-4-carboxylic acid CAS 7120-25-4

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,3-Dimethylquinoline-4-carboxylic acid.

2,3-Dimethylquinoline-4-carboxylic acid (CAS 7120-25-4), molecular formula C12H11NO2 and molecular weight 201.22 g/mol, is a CATO reference standard with documented purity and traceability.

2,3-Dimethylquinoline-4-carboxylic acid (C12H11NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 2,3-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.
