Chemical Structure
Description
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, tert-Butyl 4-(4-Ethoxy-1,1,1-trifluoro-4-oxobutan-2-yloxy)piperidine-1-carboxylate is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 369.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
tert-Butyl 4-(4-Ethoxy-1,1,1-trifluoro-4-oxobutan-2-yloxy)piperidine-1-carboxylate (CAS 1864074-89-4), molecular formula C16H26F3NO5 and molecular weight 369.38 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.
