Methyl 3-fluoro-2-methylpropanoate CAS 2253-38-5

Description

Compared with other compounds in its class, the molecular weight of 120.12 g/mol gives Methyl 3-fluoro-2-methylpropanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methyl 3-fluoro-2-methylpropanoate (CAS 2253-38-5) is a high-purity analytical reference standard with the molecular formula C5H9FO2 and a molecular weight of 120.12 g/mol.

Based on its molecular formula C5H9FO2, Methyl 3-fluoro-2-methylpropanoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 120.12 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
