Chemical Structure
Description
Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 1-(5-Chloro-2-fluorophenyl)ethan-1-ol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 174.60 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
1-(5-Chloro-2-fluorophenyl)ethan-1-ol (CAS 958653-04-8), molecular formula C8H8ClFO and molecular weight 174.60 g/mol, is a CATO reference standard with documented purity and traceability.
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.
