Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, tert-butyl 1-fluoro-3-hydroxy-cyclobutanecarboxylate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 190.21 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.
tert-butyl 1-fluoro-3-hydroxy-cyclobutanecarboxylate (CAS 2231676-35-8), molecular formula C9H15FO3 and molecular weight 190.21 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.
