Chemical Structure
Description
tert-Butyl endo-3-amino-9-azabicyclo[3.3.1]nonane-9-carboxylate (CAS 1887167-87-4) is a high-purity analytical reference standard with the molecular formula C13H24N2O2 and a molecular weight of 240.34 g/mol.
Structurally, tert-Butyl endo-3-amino-9-azabicyclo[3.3.1]nonane-9-carboxylate (C13H24N2O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 240.34 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
