Description

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 supplies 3,4-Difluor-benzylchlorid 3,4-difluorobenzyl chloride 3,4-difluorobenzyl chloride; 3,4-difluorobenzylchloride; 4-chloromethyl-1,2-difluoro-benzene; 698-80-6 EBD935305 (CAS 698-80-6), a certified reference material (molecular formula C7H5ClF2, MW 162.56 g/mol) for analytical method development and quality control.

Structurally, 3,4-Difluor-benzylchlorid 3,4-difluorobenzyl chloride 3,4-difluorobenzyl chloride; 3,4-difluorobenzylchloride; 4-chloromethyl-1,2-difluoro-benzene; 698-80-6 EBD935305 (C7H5ClF2) contains fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 162.56 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

CATO manufactures 3,4-Difluor-benzylchlorid 3,4-difluorobenzyl chloride 3,4-difluorobenzyl chloride; 3,4-difluorobenzylchloride; 4-chloromethyl-1,2-difluoro-benzene; 698-80-6 EBD935305 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.
