5-Bromo-2-hydroxypyridine-4-carboxylic acid - Introduction

Acid is an organic compound with a chemical formula of C6H4BrNO3. The structure is a product obtained by replacing the hydrogen atom on the 5th position of isonicotinic acid molecule with bromine atom and the hydrogen atom on the 2nd position with hydroxyl group.

The nature of this compound is a white crystalline solid with a unique odor. It is stable at room temperature, but decomposes at high temperatures.

The Acids are commonly used as catalysts and ligands in organic synthesis. It can be used as a ligand for organometallic catalysts and participate in various important organic reactions, such as hydrogenation, hydroxylation and sulfidation reactions. In addition, the compound can also be used to prepare other organic compounds, such as biologically active compounds and drugs.

The method for preparing a polyacid can start from isonicotinic acid. First, isonicotinic acid and bromine are reacted under certain conditions, and then the target product is obtained through acid-base neutralization and crystallization purification steps.

Regarding safety information, Acid is a toxic compound and direct contact with skin and inhalation of gases should be avoided. Appropriate protective measures should be taken during use and storage, such as gloves, protective glasses and breathing masks. At the same time, it should be stored in a dry, well-ventilated place, away from fire and oxidizing agents. In case of accidental contact or inhalation, seek medical help immediately.
