General description

Dimethyl sulfoxide-d6 (DMSO-d6) is a deuterated NMR solvent. It undergoes photodissociation to generate CD3 radical photoproducts, which have been analyzed by infrared diode laserabsorption spectroscopy. Dissociation dynamics of DMSO-d6 at 193nm was examined using photo fragment translational spectroscopy method.

Application

Dimethyl sulfoxide-d6 may be used as an NMR solvent for 1H and 13C NMR experiments.

Xylan extracted from corn cobs was used to produce mesalamine-loaded xylan microparticles (XMP5-ASA) by cross-linking polymerization using a non-hazardous cross-linking agent. The microparticles were characterized by thermal analysis (DSC/TG), X-ray diffraction (XRD), Infrared spectroscopy (FTIR-ATR) and scanning electron microscopy (SEM).
