Use	for organic synthesis, for the determination of ketones and sugars.
production method	is obtained by reduction of N-nitrosomethylaniline. The zinc powder and water were stirred to form a suspension, and a solution of N-nitrosomethylamine and glacial acetic acid was slowly added at 10-20 ° C. After addition, stirring was continued for 1H at room temperature. This was then heated to 80 °c and the unreacted zinc powder was filtered off while hot. The filtrate was cooled and an excess of 40% sodium hydroxide solution was added to redissolve the precipitated sodium hydroxide. The oil layer was separated and distilled under reduced pressure to collect the 106-109 ℃(1.73kPa) fraction, which is the finished product. The yield was more than 50%.
