Chemical Structure

Methyl bromomethanesulfonate CAS 61801-27-2 chemical structure

Description

Structurally, Methyl bromomethanesulfonate (C2H5BrO3S) contains a sulfone group, a carboxylic acid group, an ether linkage, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 189.03 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Methyl bromomethanesulfonate (CAS 61801-27-2) is a high-purity analytical reference standard with the molecular formula C2H5BrO3S and a molecular weight of 189.03 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.
