Chemical Structure

tert-Butyl 4-(2-ethoxy-1-fluoro-2-oxoethylidene)piperidine-1-carboxylate CAS 672957-85-6 chemical structure

Description

The occurrence of tert-Butyl 4-(2-ethoxy-1-fluoro-2-oxoethylidene)piperidine-1-carboxylate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies tert-Butyl 4-(2-ethoxy-1-fluoro-2-oxoethylidene)piperidine-1-carboxylate (CAS 672957-85-6), a certified reference material (molecular formula C14H22FNO4, MW 287.33 g/mol) for analytical method development and quality control.

Structurally, tert-Butyl 4-(2-ethoxy-1-fluoro-2-oxoethylidene)piperidine-1-carboxylate (C14H22FNO4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 287.33 g/mol, it falls into the medium-molecular-weight range. 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.

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.
