Chemical Structure

2-(2,5-Difluorophenyl)ethanol CAS 862255-56-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 158.15 g/mol gives 2-(2,5-Difluorophenyl)ethanol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(2,5-Difluorophenyl)ethanol (CAS 862255-56-9), molecular formula C8H8F2O and molecular weight 158.15 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 2-(2,5-Difluorophenyl)ethanol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 158.15 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).

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-(2,5-Difluorophenyl)ethanol 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.
