Chemical Structure
Description
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.
CATO supplies Tert-butyl 4-((2-fluoro-4-nitrophenyl)amino)piperidine-1-carboxylate (CAS 952285-81-3), a certified reference material (molecular formula C16H22FN3O4, MW 339.36 g/mol) for analytical method development and quality control.
Tert-butyl 4-((2-fluoro-4-nitrophenyl)amino)piperidine-1-carboxylate (C16H22FN3O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
