1-Azido-3-methylbutane (CAS 55210-77-0) is a high-purity analytical reference standard with the molecular formula C5H11N3 and a molecular weight of 113.16 g/mol.
Based on its molecular formula C5H11N3, 1-Azido-3-methylbutane contains a nitrile group; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 113.16 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.
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.
