Chemical Structure

4-[(3,4-Dichlorobenzyl)oxy]-3-methoxybenzoic acid CAS 938277-75-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-[(3,4-Dichlorobenzyl)oxy]-3-methoxybenzoic acid.

4-[(3,4-Dichlorobenzyl)oxy]-3-methoxybenzoic acid (CAS 938277-75-9), molecular formula C15H12Cl2O4 and molecular weight 327.16 g/mol, is a CATO reference standard with documented purity and traceability.

4-[(3,4-Dichlorobenzyl)oxy]-3-methoxybenzoic acid (C15H12Cl2O4) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. 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.

CATO manufactures 4-[(3,4-Dichlorobenzyl)oxy]-3-methoxybenzoic acid 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.
