Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-(Ethylsulfonyl)prop-1-ene (CAS 34008-91-8), molecular formula C5H10O2S and molecular weight 134.20 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, 3-(Ethylsulfonyl)prop-1-ene is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 134.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
