4-溴-3,5-二甲氧基苯甲醛 - Introduction
4-Bromo-3,5-dimethoxy benzaldehyde is an organic compound with the chemical formula C9H9BrO3.
Properties of the compound include:
1. Appearance: is a solid, common for white crystals.
2. Solubility: Soluble in some commonly used organic solvents, such as ethanol, ether and chloroform.
3. Melting point and boiling point: the melting point is about 80-82 ° C, and the boiling point is about 180-183 ° C.
4-Bromo-3,5-dimethoxy benzaldehyde is commonly used as an intermediate in organic synthesis reactions. It can be used in the preparation of other organic compounds, especially in the synthesis of benzoic acid compounds. Due to its high activity in synthesis, other compounds can be generated by oxidation or reduction reactions.
The method of preparing 4-Bromo-3,5-dimethoxy benzaldehyde generally includes the following steps:
1. Firstly, P-dimethoxyphenol is obtained, and bromide is added to the solvent to cause bromination reaction to generate 4-bromo -3,5-dimethoxyphenol.
2. The 4-bromo-3, 5-dimethoxyphenol is then subjected to an oxidation reaction, which is added to an oxidizing agent (e. G., hydrogen peroxide or other oxidizing agent) to obtain 4-bromo-3, 5-dimethoxybenzocresol.
3. Finally, through the oxidation reaction of aldehyde compounds, 4-Bromo-3,5-dimethoxy benzaldehyde is converted into 4-Bromo-3,5-dimethoxy benzaldehyde.
Regarding safety information, 4-Bromo-3,5-dimethoxy benzaldehyde is an organic compound, so appropriate safety measures need to be taken. During use, direct contact with skin, eyes and inhalation of vapors should be avoided. Wear protective goggles, gloves and protective masks when necessary to prevent accidental contact and inhalation. In addition, the substance should be stored in a sealed container, away from combustibles and oxidants, and avoid contact with ignition sources. In case of leakage or accident, appropriate cleaning and treatment measures shall be taken in time. If necessary, seek professional help immediately.
