Chemical Structure
Description
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.
(R)-tert-Butyl 4-(fluoromethyl)-1,2,3-oxathiazolidine-3-carboxylate 2,2-dioxide (CAS 2476729-49-2) is a high-purity analytical reference standard with the molecular formula C8H14FNO5S and a molecular weight of 255.26 g/mol.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, (R)-tert-Butyl 4-(fluoromethyl)-1,2,3-oxathiazolidine-3-carboxylate 2,2-dioxide is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 255.26 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.
