Chemical Structure

Methanedisulfonyl difluoride CAS 42148-23-2 chemical structure

Description

Owing to a sulfone group, fluorine substitution, Methanedisulfonyl difluoride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 180.15 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.

Methanedisulfonyl difluoride (CAS 42148-23-2) is a high-purity analytical reference standard with the molecular formula CH2F2O4S2 and a molecular weight of 180.15 g/mol.

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.
