1-Methylindazole - Introduction
1-methylindazole is an organic compound with the chemical formula C4H4N2CH3, which is a methylated derivative of indazole. The following is an introduction to the properties, uses, preparation and safety information of 1-methylindazole:
Nature:
1-Methylindazole is a colorless to pale yellow crystalline or powdery solid. It is less soluble in non-polar solvents, but soluble in water and some organic solvents. It is acidic and unsaturated and can react chemically with acids, substrates or other compounds.
Use:
1-Methylindazole has a variety of uses in chemical research and industry, including:
1. As an intermediate of bacteriostatic agent and fungicide, it is used to prepare compounds such as drugs and pesticides;
2. used as a chemical reaction catalyst;
3. As a chelating agent for copper and other metals, it is widely used in electroplating and metal surface treatment;
4. Used for dye synthesis and preparation of polymer additives.
Preparation Method:
1-methylindazole can be synthesized by a variety of methods, of which commonly used preparation methods include:
1. Indazole reacts with methyl iodide to generate the chloride of 1-methylindazole, which is then subjected to reduction, crystallization and purification steps to obtain the pure product;
2. The methyl group is introduced into the indazole molecule by the reaction of indazole and methyl magnesium bromide, and then 1-methylindazole is generated by acidic hydrolysis.
Safety Information:
When using 1-methylindazole, some safety measures need to be observed:
1. 1-Methylindazole is irritating and may cause eye and skin irritation. Wear appropriate protective gloves, glasses and masks during operation to avoid direct contact;
2. It should be used in a well-ventilated place and avoid inhaling its powder;
3. should be away from the fire and oxidant, to avoid the risk of fire or explosion;
4. should be stored in a dry, cool, well-ventilated place, and away from organic matter and acid.
please note that the above introduction is only an overview of the general properties, uses, preparation methods and safety information of 1-methylindazole. the specific use also needs to be operated according to the actual situation and refer to relevant professional literature.
