Benzenesulfonic acid, 2-iodo-5-methyl- - Introduction
2-iodo-5-methylbenzenesulfonic acid is an organic compound with the chemical formula C8H7IO3S. The following is a description of its nature, use, preparation and safety information:
Nature:
2-Iodo-5-methylbenzenesulfonic acid is a solid with a white crystalline form. Its melting point is about 200°C. The compounds may be soluble in organic solvents, such as alcohols and ethers, but are relatively insoluble in water.
Use:
2-iodo-5-methylbenzenesulfonic acid can be used as an important reagent in organic synthesis. It can be used to synthesize compounds with specific structures, such as drugs, pesticides and dyes.
Preparation Method:
The preparation of 2-iodo-5-methylbenzenesulfonic acid can be obtained by iodination of 2-methylbenzenesulfonyl chloride. First, iodine is subjected to an oxygen-iodine exchange reaction in the presence of 1,2-dinitrobenzenesulfonyl chloride to obtain 2-iodobenzenesulfonyl chloride. Then, 2-iodobenzenesulfonyl chloride is reacted with methylaniline to give 2-iodo-5-methylbenzenesulfonyl chloride. Finally, it is reacted with ammonia water to obtain the target product 2-iodo-5-methylbenzenesulfonic acid. The entire synthesis process needs to be carried out under appropriate conditions, and the reaction process requires the operator to have laboratory safety knowledge.
Safety Information:
2-iodo-5-methylbenzenesulfonic acid is an organic compound, and its toxicity and irritation should be paid attention. During operation, it is recommended to wear appropriate personal protective equipment, such as laboratory gloves, goggles and laboratory coats. Avoid contact with skin and eyes, such as accidental contact with skin or eyes, should immediately rinse with water. In addition, during preparation and operation, ensure that you work in a well-ventilated environment to avoid inhaling harmful gases. It is best to store the compound in a closed container, away from the fire and oxidant.
The information provided above is for reference only. The specific operation should follow the operating procedures and relevant safety guidelines of the chemical laboratory. If you need to use the compound, please seek professional advice and guidance.
