1,4-Dichloro-2-difluoromethoxy-3,5,6-trifluorobenzene CAS 1806353-98-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1,4-Dichloro-2-difluoromethoxy-3,5,6-trifluorobenzene.

1,4-Dichloro-2-difluoromethoxy-3,5,6-trifluorobenzene (CAS 1806353-98-9) is a high-purity analytical reference standard with the molecular formula C7HCl2F5O and a molecular weight of 266.98 g/mol.

Owing to a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system, 1,4-Dichloro-2-difluoromethoxy-3,5,6-trifluorobenzene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 266.98 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).

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

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.
