The introduction of DMSO
1)The
uses of industrial-grade DMSO: mainly used as solvent
in water-free organic chemical synthesis and pharmaceutical
and intermediate synthesis reaction. It can improve the reaction
speed, improve the yield of reactant, shorten the reaction time
and make reaction easier to take place.

4)The
uses of external-medical-grade DMSO: DMSO itself has
the functions of acesodyne, detumescence and dissolving extravasated
blood, and is especially effective to skin diseases. It is mainly
used as pharmaceutical additive and the carrier of drugs.
