Chemical Structure

2,2-Dichloro-1-(2,4-dichlorophenyl)ethanone CAS 2274-66-0 chemical structure

Description

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.

2,2-Dichloro-1-(2,4-dichlorophenyl)ethanone (CAS 2274-66-0) is a high-purity analytical reference standard with the molecular formula C8H4Cl4O and a molecular weight of 257.93 g/mol.

Owing to a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system, 2,2-Dichloro-1-(2,4-dichlorophenyl)ethanone is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.93 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).

As a certified reference material (CRM), 2,2-Dichloro-1-(2,4-dichlorophenyl)ethanone meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
