(3-aminophenyl)boronic acid - Introduction

3-aminophenylboronic acid monohydrate, chemical formula C6H5B(OH)2NH2 · H2O, also known as APB monohydrate. The following is a description of its nature, use, preparation and safety information:

Nature:
1. Appearance: APB monohydrate is white crystalline powder.
2. Thermal stability: APB monohydrate is stable below 150°C, but it will decompose when it exceeds this temperature.
3. Solubility: APB monohydrate is soluble in water and alcohol solvents, such as ethanol and propanol.

Use:
1. Catalyst: APB monohydrate is widely used in rhenium catalyst systems in organic synthesis, such as oxychlorination agents, proton catalysts and Friedel-Crafts reaction reagents.
2. Additives: APB monohydrate can also be used as a fluorescent dye, polymer stabilizer and Aurora Borealis luminous agent and other additives.

Method:
The preparation method of APB monohydrate is as follows:
1. Phenylboronic acid (C6H5BO2) and aminophenol (C6H6ONH2) reaction in an appropriate solvent, commonly used solvents are water or ethanol.
2. During the reaction, slowly add acid or alkali to adjust the pH value of the reaction solution to keep it within the appropriate range.
3. After completion of the reaction, the solvent was evaporated to obtain white crystals of APB monohydrate.

Safety Information:
1. APB monohydrate is a general chemical, and corresponding laboratory operating procedures and personal protective measures shall be observed.
2. Avoid contact with skin and eyes, such as contact should be immediately washed with plenty of water.
3. Avoid inhaling dust or vapor during use to prevent inhalation from damaging the respiratory system.
4. Storage should be sealed in a dry, cool place, away from the fire and oxidant.
