Chemical Structure
Description
1,1-Dimethylethyl 5-bromo-3,3-dimethyl-4-oxo-1-piperidinecarboxylate (CAS 1399183-67-5) is a high-purity analytical reference standard with the molecular formula C12H20BrNO3 and a molecular weight of 306.20 g/mol.
Based on its molecular formula C12H20BrNO3, 1,1-Dimethylethyl 5-bromo-3,3-dimethyl-4-oxo-1-piperidinecarboxylate contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 306.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
