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.
tert-Butyl (3S,4S)-3-fluoro-4-(methylamino)piperidine-1-carboxylate (CAS 2820190-99-4), molecular formula C11H21FN2O2 and molecular weight 232.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of tert-Butyl (3S,4S)-3-fluoro-4-(methylamino)piperidine-1-carboxylate (C11H21FN2O2) is characterized by an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
