Carbon-13 magnetic resonance spectroscopy of drugs. Sulfonamides.
The natural abundance 13C magnetic resonance spectra of a series of sulfonamide drugs(sulfanilamide, sulfaguanidine,sulfathiazole, sulfasuxidine, sulfadiazine, sulfamerazine, sulfamethiazine, and sulfapyridine) have been determined at 25.15 MHz employing the pulse Fourier transform technique. The chemical shefts have been assigned with the aid of off-resonance and selective proton decoupling techniques, as well as by long-range carbon-13 proton coupling patterns.
