Our product, N - methylformamide with the CAS number 123 - 39 - 7, is a factory - supplied chemical with the best price in the market. N - methylformamide is a colorless to pale - yellow liquid. Its molecular formula is C₂H₅NO, and the molecular weight is approximately 59.07 g/mol. It has a melting point of - 3.8 °C and a boiling point of 199.5 °C. The density is around 1.011 g/mL at 25 °C. This chemical is miscible with water, ethanol, and ether. It has a characteristic odor and is a polar aprotic solvent. It is a hygroscopic compound, which means it can absorb moisture from the air.
N - methylformamide has a wide range of applications in various industries. In the pharmaceutical industry, it serves as a solvent for many organic reactions. It can dissolve a variety of pharmaceutical intermediates, facilitating the synthesis of complex drug molecules. For example, it is used in the synthesis of certain antibiotics and anti - cancer drugs. In the polymer industry, it is used as a solvent for spinning polyacrylonitrile fibers. It helps in the formation of high - quality fibers with good mechanical properties. Also, in the electronics industry, it can be used for cleaning and etching printed circuit boards. It can effectively remove impurities and residues without damaging the delicate electronic components.
When using N - methylformamide, proper safety precautions should be taken. It is recommended to wear appropriate personal protective equipment, such as gloves and safety goggles. When handling it in a laboratory setting, use it in a well - ventilated area or under a fume hood to avoid inhaling its vapors. When using it as a solvent in chemical reactions, carefully measure the required amount according to the reaction stoichiometry. Add it slowly to the reaction mixture while stirring gently. After the reaction is complete, the product can be separated from the N - methylformamide by appropriate separation techniques, such as distillation or extraction. When using it for industrial applications like fiber spinning or electronics cleaning, follow the specific operating procedures and guidelines provided by the equipment manufacturers.
Case 1: Pharmaceutical Synthesis
A pharmaceutical company was synthesizing a new anti - inflammatory drug. They used N - methylformamide as a solvent for a key reaction step. The reaction required the dissolution of two reactants that were insoluble in common solvents. N - methylformamide was able to dissolve both reactants effectively, allowing the reaction to proceed smoothly. The yield of the intermediate product was significantly higher compared to using other solvents. After further purification steps, the final anti - inflammatory drug met all the quality standards.
Case 2: Polymer Fiber Production
A polymer manufacturer was producing polyacrylonitrile fibers. They switched to using N - methylformamide as the spinning solvent from a traditional solvent. The use of N - methylformamide resulted in fibers with better mechanical strength and uniformity. The fibers had a smoother surface and fewer defects, which improved the overall quality of the final textile products made from these fibers.
Case 3: Electronics Cleaning
An electronics manufacturing company was facing issues with residue on their printed circuit boards. They tested N - methylformamide as a cleaning agent. After using N - methylformamide in a controlled cleaning process, the residues on the printed circuit boards were completely removed. The electrical performance of the boards improved, and the production yield increased due to fewer defective products.
