Diazomethane is the chemical compound CH2N2 discovered by German chemist Hans von Pechmann in 1894. It is the simplest diazo compound. In the pure form at room temperature it is an extremely sensitive explosive yellow gas; thus it is almost universally used as a solution in diethyl ether. The compound is a popular methylating agent in the laboratory but it is too hazardous to be employed on an industrial scale without special precautions.
