4-IODO-PYRAZOLE-1-CARBOXYLIC ACID TERT-BUTYL ESTER - Introduction
tert-butyl (tert-butyl) is an organic compound. The following is an introduction to its nature, use, preparation and safety information:
Nature:
chemical formula: C10H14IN3O2
Molecular weight: 337.14g/mol
Appearance: Colorless to light yellow crystal or powder
Melting point: 54-56°C
Boiling point: 345.7°C
Solubility: Soluble in some organic solvents, such as ethanol, dimethylformamide and dichloromethane
Stability: relatively stable under dry conditions
Use:
tert-butyl can be used as an important intermediate in organic synthesis. It can be used in the synthesis of various pesticides, drugs and other compounds.
Preparation Method:
The preparation method of tert-butyl is more complicated. A commonly used preparation method is the reaction of 1-acetylpyrazole and iodine cyanide in acetonitrile to form 4-iodopyrazole-1-carboxylic acid ethyl ester, which is then decarboxylated by acid catalysis and isopropyl alcohol to obtain tert-butyl.
Safety Information:
tert-butyl is less toxic and dangerous, it still needs to be handled with caution. Be careful to avoid inhalation, contact with skin and eyes when using. You should work in a well-ventilated area and wear chemical goggles and gloves. If contact occurs, rinse immediately with clean water and seek medical help. When handling and storing, please observe the relevant safety regulations and keep away from ignition and flammable materials.
