Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1-Methylthio-1-propene (cis/trans mixture) (CAS 10152-77-9), molecular formula C4H8S and molecular weight 88.17 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, 1-Methylthio-1-propene (cis/trans mixture) is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 88.17 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.
