5-METHYL-4-ISOXAZOLESULPHONYL CHLORIDE - Introduction
It is an organic compound with the chemical formula C4H4ClNO3S. The following is a description of its nature, use, formulation and safety information:
Nature:
is a solid compound, colorless to yellowish crystals. It is stable at room temperature and has a strong smelly acid smell. It has a melting point of about 80-84 degrees Celsius and a boiling point of 340 degrees Celsius. The compound is insoluble in water, but soluble in polar organic solvents.
Use:
chloride is an important intermediate in organic synthesis. It is commonly used in the synthesis of drugs, pesticides and other biologically active compounds. The compounds can be used as condensation reagents and substitution reagents to participate in organic reactions such as esterification, deetherification, olefination, nucleophilic substitution, etc. It can also be used in the synthesis of antibiotics, pesticides and other biologically active compounds.
Method:
The preparation of chloride is usually obtained by reacting p-methylisoxazole (5-methylisoxazole) with sulfonyl chloride (sulfonyl chloride). The reaction is carried out under anhydrous and anaerobic conditions, typically in an organic solvent such as dichloromethane or trichloromethane.
Safety Information:
chloride is an organic compound that is irritating and corrosive. Appropriate safety precautions should be taken during use or handling, including wearing protective glasses, gloves and protective clothing. Avoid inhaling its vapors or touching the skin. In case of inadvertent inhalation or contact, wash the affected area immediately and seek medical help. At the same time, the compound should be stored in a closed container, away from fire and oxidizing agents.
