氯甲酸-4-氯苯酯 - Introduction
4-chlorophenyl chloroformate, also known as 4-chlorobenzoate, is an organic compound. The following is a description of its nature, use, formulation and safety information:
Nature:
4-chlorophenyl chloroformate is a colorless to yellowish liquid with a pungent odor. It is unstable at room temperature and will hydrolyze in a humid environment. It has a density of 1.24g/cm³ and a boiling point of 132-133°C.
Use:
4-chlorophenyl chloroformate is commonly used as a reagent in organic synthesis. It can be used as a protecting group for protecting amino and hydroxyl functional groups. In addition, it can also be used in synthetic esterification reactions and carboxylic acid esterification reactions.
Preparation Method:
4-chlorophenyl chloroformate is usually prepared by reacting chloroformic acid with chlorobenzene chloride under acidic conditions. The reaction conditions may be carried out at room temperature or may be heated to the reaction temperature.
Safety Information:
4-chlorophenyl chloroformate is a chemical in organic synthesis. It needs to be stored in a sealed container, away from fire and oxidizing agents. Care should be taken during use, such as wearing appropriate protective glasses and gloves. At the same time, avoid inhaling its vapor and avoid skin contact. If contact with skin or eyes occurs, rinse immediately with plenty of water and seek medical help.
