1. The introduction of DMSO1)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, %: ≤ 0.1Evaporation 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 StandardContent(as DMSO), %: ≥ 99.9 Crystallization point, : ≥ 18.3 Refractive index: 1.478~~1.479  Moisture, %: ≤ 0.01 UV extinction value: 275nm ≤ 0.3 285nm ≤ 0.2295nm ≤ 0.2Heavy 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 StandardContent(as DMSO), %: ≥ 99.9 Crystallization point, : ≥ 18.35 Acid value(mgKOH/g): ≤ 0.001Refractive index(20): 1.4781.479 Moisture, %: ≤ 0.001 Evaporation residue, PPM: ≤ 5. Heavy metals, %: ≤ 10
