butanoic acid, chloromethyl ester - Introduction
Chloromethyl butyrate, chemical formula C6H11ClO2, is an organic compound. The following is a description of some of its properties, uses, methods and safety information:
Nature:
1. Appearance: Chloromethyl butyrate is a colorless liquid at room temperature.
2. Solubility: It can be dissolved in organic solvents, such as ethanol and ether.
3. odor: it has a pungent smell.
Use:
1. Chemical synthesis: Chloromethyl butyrate can be used as an important intermediate in organic synthesis, such as the synthesis of compounds containing carboxyl groups.
2. Pharmaceutical field: It can be used for synthetic drugs and medical supplies, such as synthetic antibiotics and antiviral drugs.
Preparation Method:
The Chloromethyl butyrate can be obtained by reacting chloroformic acid with n-butanol. During the reaction, chloroformic acid and n-butanol are esterified in the presence of an acidic catalyst to generate Chloromethyl butyrate.
Safety Information:
1. Chloromethyl butyrate is an organic compound and should be used with caution. Follow appropriate safety procedures and wear personal protective equipment such as protective gloves and goggles.
