tert-Butyl but-3-yn-1-ylcarbamate - Introduction
Carbamic acid, 3-butynyl-, 1,1-dimethylethyl ester (9CI) is an organic compound with the following properties:
1. Appearance and properties: Carbamic acid, 3-butynyl-, 1,1-dimethylethyl ester (9CI) is a white crystalline solid.
2. Solubility: It can be dissolved in common organic solvents, such as chloroform, dimethylformamide and dichloromethane.
3. Stability: Carbamic acid, 3-butynyl-, 1,1-dimethylethyl ester (9CI) is stable under dry conditions, but it is easy to hydrolyze when wet or heated.
Carbamic acid, 3-butynyl-, 1,1-dimethylethyl ester (9CI) is mainly used as an intermediate in organic synthesis. It can be used as a protecting group or as a reactant in the synthesis of pharmaceuticals, pesticides and other organic compounds.
The method of preparing Carbamic acid, 3-butynyl-, 1,1-dimethylethyl ester (9CI) is mainly realized by esterification of butyl cyanamide and butanol. The specific steps are as follows:
1. Dissolve dicyanamide in a dry solvent, such as dimethylformamide.
2. At low temperature, add excess chloroformic acid-N-tert-butoxycarbonyl (BOC-Cl).
3. The reactants are mixed and stirred for reaction, and the reaction time is usually several hours to several days.
4. After completion of the reaction, the unreacted BOC-Cl in the reaction solution is neutralized with water or an appropriate solvent.
Note the following safety information when using Carbamic acid, 3-butynyl-, 1,1-dimethylethyl ester (9CI):
1. Avoid contact with skin, eyes and mouth. If exposed, rinse immediately with plenty of water and seek medical help.
2. In the process of operation and storage, contact with oxygen, strong acid and strong oxidant should be avoided to prevent dangerous substances or fire accidents.
3. Prepare and use with appropriate personal protective equipment, such as lab gloves, protective goggles and protective aprons.
4. Operate under safe ventilation conditions to avoid inhalation of volatile substances.
5. Keep dry and sealed during storage, away from fire and heat sources.
