Chemical Structure

3-(1,3-Benzoxazol-2-yl)benzoic acid CAS 20000-56-0 chemical structure

Description

The occurrence of 3-(1,3-Benzoxazol-2-yl)benzoic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3-(1,3-Benzoxazol-2-yl)benzoic acid (CAS 20000-56-0), a certified reference material (molecular formula C14H9NO3, MW 239.23 g/mol) for analytical method development and quality control.

3-(1,3-Benzoxazol-2-yl)benzoic acid (C14H9NO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
