Chemical Structure

4-azidobutan-2-one CAS 3777-68-2 chemical structure

Description

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.

4-azidobutan-2-one (CAS 3777-68-2), molecular formula C4H7N3O and molecular weight 113.12 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C4H7N3O, 4-azidobutan-2-one contains an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 113.12 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.
