Chemical Structure
Description
3-(N-(4-chloro-3-methylisoxazol-5-yl)sulfamoyl)-N-methoxy-N-methylthiophene-2-carboxamide (CAS 210421-71-9) is a high-purity analytical reference standard with the molecular formula C11H12ClN3O5S2 and a molecular weight of 365.81 g/mol.
3-(N-(4-chloro-3-methylisoxazol-5-yl)sulfamoyl)-N-methoxy-N-methylthiophene-2-carboxamide (C11H12ClN3O5S2) 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.
