2-溴-4-甲基苯甲酸 - Introduction
2-Bromo-4-methylbenzoic acid (2-Bromo-4-methylbenzoic acid) is an organic compound with the chemical formula C8H7BrO2.
Nature:
2-Bromo-4-methylbenzoic acid is a white crystalline solid with a characteristic benzoic acid odor. It is soluble in organic solvents (such as ethanol, chloroform, etc.) at room temperature, slightly soluble in water.
Use:
2-Bromo-4-methylbenzoic acid is an important organic synthesis intermediate, which is commonly used in the synthesis of drugs and pesticides. It can also be used for the preparation of organic light-emitting diode materials.
Preparation Method:
2-Bromo-4-methylbenzoic acid can be prepared by reacting p-toluic acid with bromine in an acid medium. The reaction conditions are generally heating in a solvent, and the reaction may be carried out using an acidic solution or an acid catalyst.
Safety Information:
2-Bromo-4-methylbenzoic acid is an organic compound and is relatively stable. However, because it is a toxic substance, it is necessary to pay attention to safety measures during use and preparation, such as wearing appropriate personal protective equipment (such as gloves, glasses, protective clothing, etc.) to avoid inhalation, ingestion or contact with skin. At the same time, store and handle them away from combustibles and oxidants, and follow correct laboratory safety procedures.
