2-Ethoxy-5-(picolinamido)benzene-1-sulfonyl chloride sulfate (CAS 820245-48-5), molecular formula C14H14ClN2O4SHO4S and molecular weight 438.85 g/mol, is a CATO reference standard with documented purity and traceability.
2-Ethoxy-5-(picolinamido)benzene-1-sulfonyl chloride sulfate (C14H14ClN2O4SHO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
