Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Propane-1,3-disulfonyl Dichloride (CAS 20686-91-3), a certified reference material (molecular formula C3H6Cl2O4S2, MW 241.11 g/mol) for analytical method development and quality control.
Based on its molecular formula C3H6Cl2O4S2, Propane-1,3-disulfonyl Dichloride contains 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 241.11 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.
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.
