5,5-Dimethoxy-1,2,3,4-tetrachlorocyclopentadiene CAS 2207-27-4

Description

Compared with other compounds in its class, the molecular weight of 263.93 g/mol gives 5,5-Dimethoxy-1,2,3,4-tetrachlorocyclopentadiene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5,5-Dimethoxy-1,2,3,4-tetrachlorocyclopentadiene (CAS 2207-27-4) is a high-purity analytical reference standard with the molecular formula C7H6Cl4O2 and a molecular weight of 263.93 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 5,5-Dimethoxy-1,2,3,4-tetrachlorocyclopentadiene is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 263.93 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).

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.
