Chemical Structure
Description
ethyl 1-fluoro-3-hydroxy-cyclobutanecarboxylate (CAS 2231675-40-2) is a high-purity analytical reference standard with the molecular formula C7H11FO3 and a molecular weight of 162.16 g/mol.
Structurally, ethyl 1-fluoro-3-hydroxy-cyclobutanecarboxylate (C7H11FO3) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 162.16 g/mol, it falls into the medium-molecular-weight range. 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.
