Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 164.54 g/mol gives 4-Chloro-2,6-difluorophenol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4-Chloro-2,6-difluorophenol (CAS 164790-68-5), a certified reference material (molecular formula C6H3ClF2O, MW 164.54 g/mol) for analytical method development and quality control.
Structurally, 4-Chloro-2,6-difluorophenol (C6H3ClF2O) contains a hydroxyl group, an ether linkage, 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 164.54 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
