2-(O-tolyl)quinoline-4-carboxylic acid CAS 174636-85-2

Description

The occurrence of 2-(O-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.

2-(O-tolyl)quinoline-4-carboxylic acid (CAS 174636-85-2) is a high-purity analytical reference standard with the molecular formula C17H13NO2 and a molecular weight of 263.29 g/mol.

2-(O-tolyl)quinoline-4-carboxylic acid (C17H13NO2) contains a steroid core, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 2-(O-tolyl)quinoline-4-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
