Chemical Structure
Description
Owing to a hydroxyl group, an ether linkage, 2-Methyl-2-vinyloxirane is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 84.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
2-Methyl-2-vinyloxirane (CAS 1838-94-4), molecular formula C5H8O and molecular weight 84.12 g/mol, is a CATO reference standard with documented purity and traceability.
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.
