Chemical Structure
Description
Ethyl 3-(chlorosulfonyl)-5-(methoxymethyl)benzoate (CAS 1154568-86-1), molecular formula C11H13ClO5S and molecular weight 292.74 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C11H13ClO5S, Ethyl 3-(chlorosulfonyl)-5-(methoxymethyl)benzoate contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 292.74 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.
