Description

Compared with other compounds in its class, the molecular weight of 184.14 g/mol gives 4,7-Difluoro-2,7b-dihydro-1aH-oxireno[2,3-c]chromene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4,7-Difluoro-2,7b-dihydro-1aH-oxireno[2,3-c]chromene (CAS 944950-67-8), molecular formula C9H6F2O2 and molecular weight 184.14 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, 4,7-Difluoro-2,7b-dihydro-1aH-oxireno[2,3-c]chromene is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 184.14 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.
