Chemical Structure
Description
Structurally, Cyclopropyl methanesulfonate (C4H8O3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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 136.17 g/mol, it falls into the low-molecular-weight range.
Cyclopropyl methanesulfonate (CAS 1260105-11-0) is a high-purity analytical reference standard with the molecular formula C4H8O3S and a molecular weight of 136.17 g/mol.
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.
