Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 162.56 g/mol gives 2,6-Difluorobenzyl Chloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,6-Difluorobenzyl Chloride (CAS 697-73-4), molecular formula C7H5ClF2 and molecular weight 162.56 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine/chlorine substitution, an aromatic ring system, 2,6-Difluorobenzyl Chloride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 162.56 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.
CATO manufactures 2,6-Difluorobenzyl Chloride 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.
