58537-99-8 - Introduction

4-Hydroxy-2, 6-dimethylbenzonium is an organic compound with the chemical formula C9H9NO and a molecular weight of 147.18g/mol. It is a colorless crystal, at room temperature soluble in ethanol, dichloromethane and ether and other organic solvents.

4-Hydroxy-2, 6-dimenthylbenzitril has certain pharmacological activity and is widely used. It can be used as an antioxidant in food, pharmaceuticals and cosmetics, which can prolong its shelf life and protect it from oxidative damage. In addition, it can also be used as a plant growth regulator, which has the effect of promoting plant growth and increasing yield.

The method for preparing 4-Hydroxy-2,6-dimethylbenzonitrile is usually obtained by heating reaction of benzonitrile and condensation reaction of o-cresol. The reaction conditions generally require the use of hydrochloric acid, acetic acid, bismuth acetate or the like as a catalyst, and the target product can be produced efficiently.

For safety information, 4-Hydroxy-2, 6-dimethylbenzonite is stable under general conditions, but may react dangerously when heated or in contact with strong oxidants. Therefore, care should be taken to avoid contact with high temperatures and oxidants during use or storage. At the same time, it may also cause irritation and damage to the eyes, skin and respiratory system. Appropriate protective measures should be taken, such as wearing protective glasses, gloves and respirators.
