Chemical Structure
Description
Owing to a hydroxyl group, an ether linkage, fluorine substitution, 3-methylbutanoyl fluoride is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 104.12 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.
3-methylbutanoyl fluoride (CAS 352-66-9), molecular formula C5H9FO and molecular weight 104.12 g/mol, is a CATO reference standard with documented purity and traceability.
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.
