Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 140.54 g/mol gives Methyl 2-chloro-3-fluoropropanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Methyl 2-chloro-3-fluoropropanoate (CAS 14442-67-2), a certified reference material (molecular formula C4H6ClFO2, MW 140.54 g/mol) for analytical method development and quality control.
Based on its molecular formula C4H6ClFO2, Methyl 2-chloro-3-fluoropropanoate contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 140.54 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.
