1,3-Dichloro-2,5-difluorobenzene CAS 2367-80-8 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

1,3-Dichloro-2,5-difluorobenzene (CAS 2367-80-8) is a high-purity analytical reference standard with the molecular formula C6H2Cl2F2 and a molecular weight of 182.98 g/mol.

Owing to fluorine/chlorine substitution, an aromatic ring system, 1,3-Dichloro-2,5-difluorobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 182.98 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).

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
