Features:
Dimethyl sulfoxide (DMSO) is know as an analgesic and non-steroidal anti-inflammatory. It is used as an effective drug delivery system and plays a role in drug design. Besides, it has many nonmedical uses, as a solvent, cleaner, pesticide, paint stripper, cryoprotectant and metal complexing agent.
Properties:
Colorless, transparent, odorless liquid in appearance. Slight bitterness and low toxicity. Its vapors are heavier than air. It is an important polar aprotic solvent that dissolves both polar and nonpolar compounds and is miscible in a wide range of organic solvents as well as water.
Usage:
DMSO is a commonly used solvent in many chemical reactions, and it is widely used in organic synthesis and industrial Usages (polymer chemistry, medicinal and agricultural chemicals) with additional uses in oxidation reactions and organic syntheses. DMSO is increasingly used in manufacturing processes to produce microelectronic devices, such as strip photoresist in TFT-LCD 'flat panel' displays. In medicine, DMSO is predominantly used as a topical analgesic, a vehicle for topical Usage of pharmaceuticals, as an anti-inflammatory and as an antioxidant. Because DMSO increases the rate of absorption of some compounds through organic tissues, including skin, it can be used as a drug delivery system. Because of its ability to dissolve many kinds of compounds, DMSO plays a role in sample management and screening operations in drug design. In biology, DMSO may also be used as a cryoprotectant, added to cell media to prevent cell death during the freezing process.
Packaging:
200L PE drum, 1000L IBC or ISO-TANK. Transport and store as flammable and toxic material.
Storage:
Store hermetically in a shady and ventilating place. Its shelf life is 12 months. It can be still used if up to standard through retest after the specified date.
