3-(2-Chlorophenyl)-1,2-oxazole-5-carboxylic acid CAS 338982-12-0

Description

3-(2-Chlorophenyl)-1,2-oxazole-5-carboxylic acid (C10H6ClNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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.

CATO supplies 3-(2-Chlorophenyl)-1,2-oxazole-5-carboxylic acid (CAS 338982-12-0), a certified reference material (molecular formula C10H6ClNO3, MW 223.61 g/mol) for analytical method development and quality control.

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.
