Product Overview
N,N-Dimethylformamide (DMF) at 99.8% purity is a high-grade solvent specifically formulated for spectroscopy applications. This colorless, hygroscopic liquid is renowned for its exceptional solvency power, making it indispensable in laboratories for dissolving a wide range of organic and inorganic compounds. Its low UV cutoff and minimal impurity profile ensure accurate spectroscopic analysis, eliminating interference in critical measurements. The solvent’s high boiling point (153°C) and thermal stability further enhance its utility in prolonged experimental setups. DMF’s polar aprotic nature allows it to dissolve both polar and nonpolar substances, making it versatile for complex sample preparations. It is also widely used as a reaction medium in organic synthesis due to its ability to stabilize reactive intermediates. The spectroscopy-grade certification guarantees minimal water content and trace impurities, ensuring reproducibility in analytical techniques. Proper handling is recommended due to its hygroscopic properties, which can affect concentration over time if exposed to moisture. This product is packaged in airtight containers to maintain its purity and extend shelf life.
FAQs
1. What is the shelf life of N,N-Dimethylformamide 99.8% when stored properly?
When stored in a tightly sealed container at room temperature, away from moisture and direct sunlight, this product maintains its specifications for up to 24 months from the date of manufacture.
2. Is this DMF compatible with plastic labware like polypropylene or PTFE?
DMF can dissolve certain plastics, including polystyrene and acrylics. Use glass or PTFE-coated containers for long-term storage or reactions to prevent contamination.
3. Are there any safer alternatives to DMF for similar applications?
Alternatives like DMSO (Dimethyl sulfoxide) or acetonitrile can be used depending on the application, though they may have different solvency properties and boiling points.
4. How should I dispose of unused or expired DMF?
DMF should be disposed of as hazardous waste according to local environmental regulations. Neutralize with a compatible reagent or consult a licensed waste disposal service.
5. Does this product require any special handling precautions?
Yes, DMF is hygroscopic and absorbs moisture quickly. Always use in a fume hood, wear protective gloves, and avoid inhalation or skin contact due to its potential toxicity.
