Chemical Structure
Description
Tert-butyl 2,3,6,7-tetrahydro-1H-azepine-1-carboxylate (CAS 317336-73-5) is a high-purity analytical reference standard with the molecular formula C11H19NO2 and a molecular weight of 197.27 g/mol.
Based on its molecular formula C11H19NO2, Tert-butyl 2,3,6,7-tetrahydro-1H-azepine-1-carboxylate contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 197.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
