Chemical Structure
Description
The occurrence of 4-[(2-Chloro-4-fluorobenzyl)oxy]-3-methoxybenzoyl chloride 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.
4-[(2-Chloro-4-fluorobenzyl)oxy]-3-methoxybenzoyl chloride (CAS 1160250-56-5), molecular formula C15H11Cl2FO3 and molecular weight 329.15 g/mol, is a CATO reference standard with documented purity and traceability.
4-[(2-Chloro-4-fluorobenzyl)oxy]-3-methoxybenzoyl chloride (C15H11Cl2FO3) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 4-[(2-Chloro-4-fluorobenzyl)oxy]-3-methoxybenzoyl 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.
