3,4-Dichloro-5-(difluoromethoxy)benzyl chloride CAS 1803790-23-9

Description

The occurrence of 3,4-Dichloro-5-(difluoromethoxy)benzyl chloride is closely related to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 3,4-Dichloro-5-(difluoromethoxy)benzyl chloride (CAS 1803790-23-9), a certified reference material (molecular formula C8H5Cl3F2O, MW 261.48 g/mol) for analytical method development and quality control.

Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 3,4-Dichloro-5-(difluoromethoxy)benzyl chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 261.48 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 3,4-Dichloro-5-(difluoromethoxy)benzyl 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.
