2,2-Dichloro-1,1-bis(4-chlorophenyl)ethanol CAS 3567-18-8

Description

The occurrence of 2,2-Dichloro-1,1-bis(4-chlorophenyl)ethanol is closely related to a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2,2-Dichloro-1,1-bis(4-chlorophenyl)ethanol (CAS 3567-18-8) is a high-purity analytical reference standard with the molecular formula C14H10Cl4O and a molecular weight of 336.04 g/mol.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system, 2,2-Dichloro-1,1-bis(4-chlorophenyl)ethanol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 336.04 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).
