Chemical Structure

Methyl 2-(3-chloro-4-fluorobenzoyl)benzoate CAS 1443349-23-2 chemical structure

Description

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.

CATO supplies Methyl 2-(3-chloro-4-fluorobenzoyl)benzoate (CAS 1443349-23-2), a certified reference material (molecular formula C15H10ClFO3, MW 292.69 g/mol) for analytical method development and quality control.

Methyl 2-(3-chloro-4-fluorobenzoyl)benzoate (C15H10ClFO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, a polycyclic aromatic system. 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 manufactures Methyl 2-(3-chloro-4-fluorobenzoyl)benzoate 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.
