Chemical Structure

2-(Chloromethyl)thiirane CAS 3221-15-6 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 108.59 g/mol gives 2-(Chloromethyl)thiirane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

2-(Chloromethyl)thiirane (CAS 3221-15-6) is a high-purity analytical reference standard with the molecular formula C3H5ClS and a molecular weight of 108.59 g/mol.

Owing to sulfur-containing functionality, chlorine substitution, 2-(Chloromethyl)thiirane is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 108.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
