Storage method
This product should be sealed and stored in a cool, dry place away from light.
Synthesis method
Will2-Amino-5-Chlorine–Diphenyl Reflux reaction of ketone and hydroxylamine hydrochloride in ethanol10hours, get2-Amino -5-Chlorine–benzophenone oxime, and then cyclization and expansion Obtained by ring. The crude product is recrystallized with ethanol and decolorized with activated carbon to obtain the finished product.
Purpose
This product is a weak tranquilizer with sedative, anti-anxiety, anti-convulsant and muscle relaxant effects. Mainly used to treat anxiety, obsessive-compulsive neurosis, neurasthenia, insomnia and hypertension. Combined with other anti-epileptic drugs, it can suppress major or minor epileptic seizures. Taking large amounts over a long period of time can lead to addiction.
