Chemical Structure

2,3-Dichloro-4-(difluoromethoxy)benzyl chloride CAS 1807036-65-2 chemical structure

Description

Based on its molecular formula C8H5Cl3F2O, 2,3-Dichloro-4-(difluoromethoxy)benzyl chloride contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 261.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO supplies 2,3-Dichloro-4-(difluoromethoxy)benzyl chloride (CAS 1807036-65-2), a certified reference material (molecular formula C8H5Cl3F2O, MW 261.48 g/mol) for analytical method development and quality control.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
