Chemical Structure

3-Aminocyclobutan-1-one CAS 4640-43-1 chemical structure

Description

3-Aminocyclobutan-1-one (CAS 4640-43-1) is a high-purity analytical reference standard with the molecular formula C4H7NO and a molecular weight of 85.10 g/mol.

Owing to an amide group, a hydroxyl group, an ether linkage, 3-Aminocyclobutan-1-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 85.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
