111829-72-2 - Introduction
4-Bromo-2, 6-dichlorobenzaldehyde is an organic compound. The following is a description of its nature, use, preparation and safety information:
Nature:
4-Bromo-2, 6-dichlorobenzaldehyde is a white crystalline solid with a special benzaldehyde odor. It is hardly soluble in water at normal temperature, but easily soluble in organic solvents such as alcohols, ethers and ketones. The compound is stable to light and air, but decomposes when heated.
Use:
4-Bromo-2, 6-dichlorobenzaldehyde is commonly used in organic synthesis reactions, especially in the field of pesticides and pharmaceuticals. It can be used as an intermediate in the synthesis of new insecticides, fungicides, fungicides and glyphosate herbicides.
Preparation Method:
4-bromo-2, 6-dichlorobenzaldehyde is usually prepared by bromination reaction of benzaldehyde. First, benzaldehyde is reacted with hydrogen bromide at an appropriate temperature and pressure to form 4-bromobenzoic acid. The 4-bromobenzoic acid is then reacted with thionyl chloride to give 4-bromo-2, 6-dichlorobenzoyl chloride. Finally, the acid chloride is reacted with water or an alcohol to give the desired product, 4-bromo-2, 6-dichlorobenzaldehyde.
Safety Information:
4-Bromo-2, 6-dichlorobenzaldehyde is an organic halogenated ketone compound with certain toxicity. Wear protective gloves, goggles and protective clothing when using. Avoid contact with skin, eyes and respiratory tract. Fire and high temperatures should be avoided during use and storage. In the event of accidental inhalation or exposure, clean the affected area immediately and seek medical help. When stored, it should be kept in a cool, dry and well-ventilated place, away from fire and flammable substances.
