Dimethyl sulfoxide (ДМСО) and N,N-диметилформамид (ДМФ) are both dipolar aprotic solvents with similar physical properties. DMSO is less toxic than DMF, and is considered a safer replacement.
Н,N-диметилформамид (ДМФ) and Dimethyl Sulfoxide (ДМСО) are two powerful solvents that play pivotal roles in the chemical industry. Their unique properties, versatility, and wide-ranging applications make them indispensable in the manufacturing of pharmaceuticals, пластмассы, текстиль, and numerous other products.
Understanding N,N-диметилформамид (ДМФ):
Н,N-Dimethylformamide by Китай Н,N-Dimethylformamide manufacturer, commonly known as DMF, is an organic compound belonging to the amide family. Here are its key properties and characteristics:
Характеристики:
- Бесцветный, hygroscopic liquid with a mild odor
- Высокая точка кипения (153°С) and low freezing point (-61°С)
- Excellent solubility for a wide range of organic and inorganic compounds
- Polar aprotic solvent with high dielectric constant
Приложения:
- Widely used in the production of polyurethane and synthetic fibers
- Serves as a solvent in the manufacture of pharmaceuticals, красители, and pesticides
- Employed in the electronics industry for cleaning and degreasing
- Used as a reaction medium in various chemical processes
Exploring Dimethyl Sulfoxide (ДМСО) к China Dimethyl Sulfoxide supplier:
Chemical structure: DMSO has two methyl groups attached to sulfur oxide (S=O). DMF has two methyl groups attached to a nitrogen atom that is attached to a formyl group (С(=O)ЧАС).
Physical properties:
- Точка кипения: DMSO has a boiling point of 189°C, while DMF has a boiling point of 153°C.
- Color: DMF is a colorless-to-yellow liquid.
- Запах: DMF has a characteristic odor.
- Плотность: DMF is slightly less dense than water.
- точка возгорания: DMF has a flash point of 136°F.
Приложения:
- Widely used in the pharmaceutical industry as a solvent and penetration enhancer
- Employed in the manufacture of plastics, текстиль, и клеи
- Serves as a solvent in the production of paints, покрытия, and inks
- Used as a cryoprotectant in the preservation of biological samples
Comparing Between DMSO And DMF
ДМСО: Can be given orally, intravenously, or topically. It can also be used as a cryoprotectant for human tissues.
ДМФ: Is a better extractant than DMSO–acetone for chlorococcalean species.
Safety Considerations For Both N,N-Dimethylformamide And Dimethyl Sulfoxide
While DMF and DMSO are valuable solvents, it’s crucial to prioritize safety measures when handling them:
- Proper Ventilation: Ensure adequate ventilation to prevent inhalation of vapors.
- Protective Equipment: Wear appropriate protective clothing, gloves, and eye protection to minimize skin contact and exposure.
- Handling Precautions: Handle DMF and DMSO in well-ventilated areas away from heat sources and open flames.
- Storage and Disposal: Store these solvents in tightly sealed containers and dispose of them responsibly according to local regulations.
