Chemical Structure
Description
Based on its molecular formula C2H4ClNO4S, 2-Nitroethane-1-sulfonyl chloride contains an amide group, a sulfone group, a carboxylic acid group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 173.58 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.
2-Nitroethane-1-sulfonyl chloride (CAS 97925-84-3) is a high-purity analytical reference standard with the molecular formula C2H4ClNO4S and a molecular weight of 173.58 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.
