Product Overview
N,N-Dimethylformamide (DMF) USP is a high-purity, polar aprotic solvent widely used in laboratory settings for its exceptional solvating properties. This colorless, hygroscopic liquid boasts a high boiling point (153°C) and low volatility, making it ideal for applications requiring stable reaction conditions. Its USP-grade certification ensures minimal impurities, including water content below 0.1%, which is critical for sensitive chemical processes. DMF exhibits excellent miscibility with water and most organic solvents, facilitating homogeneous reactions and efficient extraction procedures. The solvent’s ability to dissolve both polar and nonpolar compounds makes it versatile for peptide synthesis, polymer processing, and pharmaceutical formulations. Its low viscosity and high dielectric constant further enhance its utility in electrochemical studies and as a reaction medium. When handled properly, DMF maintains stability under normal storage conditions, though it requires protection from moisture and light to prevent degradation. This grade meets stringent quality standards, ensuring reproducible results in analytical and synthetic applications.
FAQs
1. What is the shelf life of N,N-Dimethylformamide USP when stored properly?
When stored in a tightly sealed container away from light and moisture at room temperature, N,N-Dimethylformamide USP typically maintains its specified purity for 24 months from the date of manufacture. Regular quality checks are recommended for long-term storage.
2. Can this DMF grade be used as a substitute for spectroscopic-grade DMF in UV-Vis applications?
While USP-grade DMF offers high purity, spectroscopic-grade DMF undergoes additional purification to minimize UV-absorbing impurities. For critical UV-Vis applications, spectroscopic-grade is preferred, though this USP grade may suffice for less sensitive measurements.
3. What precautions should be taken when disposing of DMF waste?
DMF should be collected in designated solvent waste containers and disposed of through licensed hazardous waste handlers. Never pour DMF down drains or mix with incompatible waste streams, as it may form toxic byproducts during treatment.
4. How does the water content in this USP-grade DMF compare to analytical-grade DMF?
USP-grade DMF typically contains less than 0.1% water, which is comparable to most analytical-grade specifications. However, for applications requiring ultra-low water content (e.g., moisture-sensitive reactions), further drying with molecular sieves may be necessary.
5. Is this DMF compatible with standard laboratory glassware and plastic containers?
DMF is compatible with borosilicate glass and high-density polyethylene (HDPE) containers. Avoid prolonged storage in polystyrene or polypropylene containers, as DMF may cause swelling or leaching. Always use containers with PTFE-lined caps to prevent contamination.
