Chemical Structure
Description
Structurally, 2-Ethylthiirane (C4H8S) contains sulfur-containing functionality. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 88.17 g/mol, it falls into the low-molecular-weight range.
2-Ethylthiirane (CAS 3195-86-6), molecular formula C4H8S and molecular weight 88.17 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.
