Chemical Structure

Methyl 4-(4-chlorophenyl)-2-fluorobenzoate CAS 1820705-31-4 chemical structure

Description

The occurrence of Methyl 4-(4-chlorophenyl)-2-fluorobenzoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methyl 4-(4-chlorophenyl)-2-fluorobenzoate (CAS 1820705-31-4), molecular formula C14H10ClFO2 and molecular weight 264.68 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Methyl 4-(4-chlorophenyl)-2-fluorobenzoate (C14H10ClFO2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 Methyl 4-(4-chlorophenyl)-2-fluorobenzoate 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.
