Chemical Structure
Description
Tert-butyl 7-hydroxy-3-oxa-9-azabicyclo[3.3.1]Nonane-9-carboxylate (CAS 1779457-66-7) is a high-purity analytical reference standard with the molecular formula C12H21NO4 and a molecular weight of 243.30 g/mol.
Based on its molecular formula C12H21NO4, Tert-butyl 7-hydroxy-3-oxa-9-azabicyclo[3.3.1]Nonane-9-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 243.30 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.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
