Methoxytetramethylpiperidineoxyl - Introduction
Methoxytetramethylpiperidineoxyl, often abbreviated as MTMPO or MeO-TEMPO, is an organic free radical compound. Its chemical formula is C9H19NO2 and its molecular weight is 173.26.
MTMPO is an organic compound with a stable free radical structure and has the appearance of a light yellow solid. It is a strong oxidant and can react with many organic and inorganic substances. It is stable at room temperature, but will accelerate decomposition under high temperature and light conditions.
One of the main uses of MTMPO is as a catalyst, especially in oxidation reactions in organic synthesis. It can catalyze the oxidation of alcohols to ketones or carboxylic acids, and can also promote the oxidation of amines to ketones and the oxidation of hydrocarbons to ketones. In addition, MTMPO can also be used as a material in organic batteries, with good charge transport properties.
A common method for preparing MTMPO is to generate MTMPO by reacting piperidine with p-methoxybenzonitrone to generate piperidine N-waste. During the preparation process, it is necessary to pay attention to the safety of the operation, ensure that it is carried out under well-ventilated conditions, and follow the corresponding protective measures.
The safety information about MTMPO, like all organic compounds, should be handled properly. In the use or storage of MTMPO should be kept away from flammable materials, and avoid contact with oxidants, strong acids, strong bases and other substances. Inhalation, contact with skin and eyes should be avoided, and in case of accidental contact, rinse immediately with plenty of water.
Generally speaking, MTMPO is an important organic free radical compound, which has a wide range of applications in the field of organic synthesis, but its safety should be paid attention to when it is used.
