Chemical Structure
Description
CATO supplies Ethyl (R)-3-(4,4-difluoropyrrolidin-2-yl)propanoate (CAS 2869831-64-9), a certified reference material (molecular formula C9H15F2NO2, MW 207.22 g/mol) for analytical method development and quality control.
Based on its molecular formula C9H15F2NO2, Ethyl (R)-3-(4,4-difluoropyrrolidin-2-yl)propanoate contains an amide group, 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 207.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
