tert-Butylmaleimide - Introduction
N-tert-butylmaleimide(N-tert-butylmaleimide) is an organic compound whose chemical formula is C8H11NO2.
Nature, N-tert-butylmaleimide is a solid crystal, colorless to light yellow. It has a high melting point and boiling point, can be stable at room temperature. This compound is insoluble in water and soluble in some common organic solvents such as ethanol, diethyl ether and dichloromethane.
The main application of N-tert-butylmaleimide is as chemical reagents and intermediates. It can be used in the synthesis of compounds containing imide functional groups, such as polymers, drugs, dyes and polymer surface modifiers. In addition, it can also be used as a capture reagent for reactive entities for specific conversion reactions in organic synthesis.
The process for preparing N-tert-butylmaleimide is generally accomplished by reacting maleic acid with tert-butylamine. The reaction can be carried out at room temperature or under slight heating, and then the target product can be obtained by crystallization purification.
When using the N-tert-butylmaleimide, you need to pay attention to some safety matters. Since it is a chemical, good laboratory practices must be followed, such as wearing personal protective equipment and operating in a well-ventilated area. In addition, N-tert-butylmaleimide may be irritating to the eyes and skin, so avoid contact with eyes and skin when using it. If you feel uncomfortable, rinse with water immediately and seek medical advice. Most importantly, store N-tert-butylmaleimide in dry, cool and sealed containers, away from fire sources and combustibles.
