FEMA 3149 - Introduction
3-Ethyl-2,5-diMethylpyrazine is an organic compound with the chemical formula C8H11N. Its nature is as follows:
1. Appearance: 3-Ethyl-2,5-diMethylpyrazine is white crystal or crystalline powder.
2. Solubility: soluble in common organic solvents, such as ethanol, ether, insoluble in water.
3. Melting Point: about 70-72 ° C.
4. Stability: relatively stable at room temperature, but need to avoid direct sunlight.
3-Ethyl-2,5-diMethylpyrazine is mainly used in the following aspects:
1. Pesticide ingredients: can be used as active ingredients or intermediates of pesticides, with insecticidal and bactericidal effects, and can be used in agricultural fields such as farmland and orchards.
2. Pharmaceutical synthesis: can be used for the synthesis of quasi adrenaline drugs, such as isoproterenol.
3. Chemical Research: 3-Ethyl-2,5-diMethylpyrazine can also be used in the field of organic synthesis, such as as reducing agent, Catalyst, etc.
There are many methods for preparing 3-Ethyl-2,5-diMethylpyrazine. One commonly used method is to react 2,5-dimethylpyrazine with acetaldehyde. The specific steps are as follows: firstly, 2,5-dimethylpyrazine and acetaldehyde are reacted in a suitable solvent, and the reaction temperature is generally room temperature or slightly higher than room temperature. After completion of the reaction, the 3-Ethyl-2,5-diMethylpyrazine product is obtained by crystallization or other suitable separation methods.
When using and handling 3-Ethyl-2,5-diMethylpyrazine, the following safety information should be paid attention:
1. Protective measures: in the operation process, should wear appropriate protective glasses, gloves and laboratory goggles, in order to avoid contact with the eyes, skin, to avoid inhalation of the vapor.
2. Ventilation conditions: Operation should be carried out in a well-ventilated place to avoid the accumulation of harmful substances.
3. Storage conditions: 3-Ethyl-2,5-diMethylpyrazine should be stored in a dry, dark place, and away from fire and oxidant.
4. Waste treatment: according to local environmental regulations, waste should be safely disposed of, and should not be dumped into sewers or other environments at will.
