Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 295.12 g/mol gives 4-Chloro-2-formylphenyl 4-chlorobenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Chloro-2-formylphenyl 4-chlorobenzoate (CAS 431933-38-9), a certified reference material (molecular formula C14H8Cl2O3, MW 295.12 g/mol) for analytical method development and quality control.
4-Chloro-2-formylphenyl 4-chlorobenzoate (C14H8Cl2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. It is notably hygroscopic, 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.
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.
As a certified reference material (CRM), 4-Chloro-2-formylphenyl 4-chlorobenzoate 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.
