Chemical Structure

Methyl chlorosulfonate CAS 812-01-1 chemical structure

Description

The occurrence of Methyl chlorosulfonate is closely related to a sulfone group, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Methyl chlorosulfonate (CAS 812-01-1) is a high-purity analytical reference standard with the molecular formula CH3ClO3S and a molecular weight of 130.55 g/mol.

Based on its molecular formula CH3ClO3S, Methyl chlorosulfonate contains a sulfone group, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 130.55 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
