Chemical Structure
Description
Based on its molecular formula C17H29BFNO3Si, (3-(4-((Tert-butyldimethylsilyl)oxy)piperidin-1-yl)-5-fluorophenyl)boronic acid contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 353.31 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
(3-(4-((Tert-butyldimethylsilyl)oxy)piperidin-1-yl)-5-fluorophenyl)boronic acid (CAS 1704073-45-9), molecular formula C17H29BFNO3Si and molecular weight 353.31 g/mol, is a CATO reference standard with documented purity and traceability.
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.
