Chemical Structure

Methyl 3,6-dichloro-2-(difluoromethoxy)benzoate CAS 1804516-35-5 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 Methyl 3,6-dichloro-2-(difluoromethoxy)benzoate.

Methyl 3,6-dichloro-2-(difluoromethoxy)benzoate (CAS 1804516-35-5) is a high-purity analytical reference standard with the molecular formula C9H6Cl2F2O3 and a molecular weight of 271.04 g/mol.

Methyl 3,6-dichloro-2-(difluoromethoxy)benzoate (C9H6Cl2F2O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, 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), Methyl 3,6-dichloro-2-(difluoromethoxy)benzoate 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.
