Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
tert-butyl (3S)-4,4-difluoro-3-hydroxypiperidine-1-carboxylate (CAS 1620656-08-7), molecular formula C10H17F2NO3 and molecular weight 237.24 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C10H17F2NO3, tert-butyl (3S)-4,4-difluoro-3-hydroxypiperidine-1-carboxylate 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 237.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
