Chemical Structure
Description
CATO supplies 4-[(3,4-Dichlorobenzyl)oxy]-3-ethoxybenzoyl chloride (CAS 1160251-29-5), a certified reference material (molecular formula C16H13Cl3O3, MW 359.63 g/mol) for analytical method development and quality control.
4-[(3,4-Dichlorobenzyl)oxy]-3-ethoxybenzoyl chloride (C16H13Cl3O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-[(3,4-Dichlorobenzyl)oxy]-3-ethoxybenzoyl chloride 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.
