Chemical Structure
Description
Acetic methylcarbamothioic anhydride (C4H7NO2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
Acetic methylcarbamothioic anhydride (CAS 89730-51-8), molecular formula C4H7NO2S and molecular weight 133.17 g/mol, is a CATO reference standard with documented purity and traceability.
