Difluoroacetic anhydride CAS 401-67-2

Description

Compared with other compounds in its class, the molecular weight of 174.05 g/mol gives Difluoroacetic anhydride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Difluoroacetic anhydride (CAS 401-67-2), molecular formula C4H2F4O3 and molecular weight 174.05 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, Difluoroacetic anhydride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 174.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
