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 3-(bromomethyl)-3-fluoropiperidine-1-carboxylate (CAS 1262409-57-3) is a high-purity analytical reference standard with the molecular formula C11H19BrFNO2 and a molecular weight of 296.18 g/mol.
tert-butyl 3-(bromomethyl)-3-fluoropiperidine-1-carboxylate (C11H19BrFNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
