Chemical Structure

2-(4-Hydroxy-3-methylbenzoyl)benzoic acid CAS 51671-72-8 chemical structure

Description

The occurrence of 2-(4-Hydroxy-3-methylbenzoyl)benzoic acid is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2-(4-Hydroxy-3-methylbenzoyl)benzoic acid (CAS 51671-72-8), a certified reference material (molecular formula C15H12O4, MW 256.25 g/mol) for analytical method development and quality control.

Based on its molecular formula C15H12O4, 2-(4-Hydroxy-3-methylbenzoyl)benzoic acid contains a flavonoid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 256.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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-(4-Hydroxy-3-methylbenzoyl)benzoic 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.
