Chemical Structure
Description
2-Methyl-oxetan-3-one (CAS 87385-83-9) is a high-purity analytical reference standard with the molecular formula C4H6O2 and a molecular weight of 86.09 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2-Methyl-oxetan-3-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 86.09 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
