How many signals will be obserred in the llMR spectra of N, N-dimethyl formanide at low temperature?
Answers
Answer:
Dimethylformamide is used as an industrial solvent and in the production of fibers, films, and surface coatings. Acute (short-term) exposure to dimethylformamide has been observed to damage the liver in animals and in humans. Symptoms of acute exposure in humans include abdominal pain, nausea, vomiting, jaundice, alcohol intolerance, and rashes. Chronic (long-term) occupational exposure to dimethylformamide by inhalation has resulted in effects on the liver and digestive disturbances in workers. Human studies suggested a possible association between dimethylformamide exposure and testicular cancer, but further studies failed to confirm this relationship. EPA has not classified dimethylformamide with respect to its carcinogenicity.
