(4-METHYL-3-PYRIDINYL)-BORONIC ACID - Introduction
4-Methylpyridine-3-boronic acid is an organic boron compound with the chemical formula C6H8BNO2. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: 4-Methylpyridine-3-boronic acid is colorless to yellowish crystal.
-Solubility: It can be dissolved in water, but also soluble in organic solvents such as methanol, ethanol and two methyl chloride.
-Stability: It is relatively stable, but it will decompose at high temperatures.
Use:
- 4-Methylpyridine-3-boronic acid is commonly used in the synthesis of boron-related compounds in organic synthesis. It can be used as a source of boron and play the role of catalyst, stabilizer and promoter in the reaction.
-It can also be used in electrochemical applications, such as as an electrolyte additive or an electrolyte for lithium-ion batteries.
Method:
- 4-Methylpyridine-3-boronic acid is usually prepared by the following two methods:
1. Add alkaline borate to 4-methylpyridine and react.
2. The boric acid ester of 4-methyl pyridine was synthesized first, and then the acid catalyst was added for hydrolysis reaction.
Safety Information:
- 4-Methylpyridine-3-boronic acid has low toxicity, but it is still necessary to pay attention to safety when using it:
-Avoid skin contact and inhalation, should wear appropriate protective measures, such as gloves and masks.
-Clean contaminated tools and equipment in time after use.
-Avoid contact with oxidants and strong acids during storage to avoid fire or harmful gas generation.
Please note that this is only a brief introduction. More detailed and specific information can be found in the relevant literature and materials.
