Chemical Structure

4-(4-Chlorophenyl)-2-hydroxybenzoic acid CAS 1261995-96-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 248.66 g/mol gives 4-(4-Chlorophenyl)-2-hydroxybenzoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-(4-Chlorophenyl)-2-hydroxybenzoic acid (CAS 1261995-96-3), a certified reference material (molecular formula C13H9ClO3, MW 248.66 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 4-(4-Chlorophenyl)-2-hydroxybenzoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 248.66 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures 4-(4-Chlorophenyl)-2-hydroxybenzoic 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.
