Properties and stability
1. It is irritating to the eyes, respiratory system and skin. If used in large quantities, appropriate protective clothing should be worn. In case of contact with eyes, rinse immediately with plenty of water and seek medical treatment.
Storage method
None yet
Synthesis method
Pour ethylene oxide gas into trimethylamine to react to obtain trimethylamine ethanol. The latter is brominated with hydrobromic acid, acylated with acetic anhydride, and finally recrystallized from ethanol to obtain this product.
Purpose
1. Used as a substrate for measuring acetylcholinesterase; clinically used as a cholinergic drug.
2. Used for biochemical research, etc.
