AURORA 23318 - Introduction

acid (acid) is an organic compound with the chemical formula C6H5NO3. It is a colorless crystalline solid, stable at room temperature.

Ion acid is hygroscopic and soluble in water and most organic solvents.

This compound has a variety of uses. First, it is widely used as a starting point for organic synthesis. It can be used as an intermediate in the preparation of other organic compounds, and plays an important role in the synthesis of drugs and pesticides.

In addition, acid can also be used as a metal complexing agent for catalytic reactions containing transition metal ions or the preparation of metal complexes.

In the preparation of pyridine acid, pyridine is usually used as raw material and obtained through a series of chemical reactions. The specific preparation method can be pyridine nitric acid reaction to produce nitropyridine compounds, and then acid and pyridine by reduction and carboxylation reaction.

you need to pay attention to safety when handling acid. Because it is irritating, it should be rinsed with water when in contact with the skin, eyes, or respiratory tract. Wear appropriate personal protective equipment such as lab gloves and goggles when used in a laboratory environment. In addition, high temperatures and sources of ignition need to be avoided when storing and transporting the compound.
