1. 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), % : ≥ 99.8
Crystallization point, : ≥ 18.10
Acid value (0.1N/ml NaOH/50g): ≤ 0.01
Moisture, %: ≤ 0.1
Evaporation residue, PPM: ≤ 5
Heavy metals, %: ≤ 10.
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), %: ≥ 99.9
Crystallization point, : ≥ 18.3
Refractive index: 1.478~~1.479
Moisture, %: ≤ 0.01
UV extinction value: 275nm ≤ 0.3
285nm ≤ 0.2
295nm ≤ 0.2
Heavy metals, ppm: ≤ 10
Specific gravity(20): 1.100-1.104
Acid value(0.1N/ml NaOH/50g): ≤ 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), %: ≥ 99.9
Crystallization point, : ≥ 18.35
Acid value(mgKOH/g): ≤ 0.001
Refractive index(20): 1.4781.479
Moisture, %: ≤ 0.001
Evaporation residue, PPM: ≤ 5.
Heavy metals, %: ≤ 10

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:
Item Index Standard
Content(as DMSO), %: ≥ 99.9
Crystallization point, : ≥ 18.3
Refractive index: 1.478-1.479
Moisture, %: ≤ 0.2
UV extinction value: 275nm ≤ 0.3
285nm ≤ 0.2
295nm ≤ 0.2
Heavy metals, ppm : ≤ 10
Specific gravity (20): 1.100-1.104
Acid value(0.1N/ml NaOH/50g): ≤ 5.0
