Chemical Structure
Description
CATO supplies Methyl 2-((2-chloroethyl)sulfonyl)acetate (CAS 113207-11-7), a certified reference material (molecular formula C5H9ClO4S, MW 200.64 g/mol) for analytical method development and quality control.
Owing to a carbohydrate-derived structure, a sulfone group, chlorine substitution, Methyl 2-((2-chloroethyl)sulfonyl)acetate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 200.64 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.
