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.
The quality and
technical index:
Content(as DMSO), % : ≥ *9.8
Crystallization point, : ≥ *8.*0
Acid value (0.1N/ml NaOH/*0g): ≤ 0.*1
Moisture, %: ≤ 0.1
Evaporation residue, PPM: ≤ 5Â
Heavy metals, %: ≤ *0.
2)The uses of medical-grade DMSO: mainly used as solvent in
pharmaceutical
and intermediate
synthesis reaction, as medical solvent and the carrier of drugs. It
can improve the reaction speed and improve the yield of
reactant.
The quality and technical index:
Item Index Standard
Content(as DMSO), %: ≥ *9.9
Crystallization point, : ≥ *8.3Â
Refractive index: 1.**8~~1.**9Â
Moisture, %: ≤ 0.*1
UV extinction value: **5nm ≤ 0.3
**5nm ≤ 0.2
**5nm ≤ 0.2
Heavy metals, ppm: ≤ *0
Specific gravity(*0): 1.****1.**4
Acid value(0.1N/ml NaOH/*0g): ≤ 5.0
3)The uses of anhydrous-grade DMSO: mainly used as solvent in
pharmaceutical and intermediate synthesis reaction, as medical
solvent and the carrier of drugs. It can improve the reaction speed
and improve the yield of reactant.
The quality and technical index:
Item Index Standard
Content(as DMSO), %: ≥ *9.9
Crystallization point, : ≥ *8.*5
Acid value(mgKOH/g): ≤ 0.**1
Refractive index(*0): 1.***1.**9
Moisture, %: ≤ 0.**1
Evaporation residue, PPM: ≤ 5.
Heavy metals, %: ≤ *0
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.
The quality and
technical index:

Refractive index: 1.****1.**9
Moisture, %: ≤ 0.2
UV extinction value: **5nm ≤ 0.3
**5nm ≤ 0.2
**5nm ≤ 0.2
