(S)-2-Bromo-1-(2,4-dichlorophenyl)ethanol CAS 187164-20-1

Description

The occurrence of (S)-2-Bromo-1-(2,4-dichlorophenyl)ethanol is closely related to a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-2-Bromo-1-(2,4-dichlorophenyl)ethanol (CAS 187164-20-1), molecular formula C8H7BrCl2O and molecular weight 269.95 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system, (S)-2-Bromo-1-(2,4-dichlorophenyl)ethanol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 269.95 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.
