Properties and stability

basic properties

White or light yellow crystalline powder. Pink point 213-216℃. 1g of this product is soluble in about 400ml of chloroform; 100ml of ether; 120ml of ethanol, and is almost insoluble in water. It tastes slightly bitter and almost odorless. It is easy to change when exposed to sunlight.

Storage method

None yet

Synthesis method

Brief description of production methods

Isatin is prepared into a sodium salt, which is ring-opened to form sodium anthranilate, and then cyclized with acetophenone to obtain cinchofen sodium, which can be acidified with acetic acid or hydrochloric acid to obtain cinchofen

Purpose

Purpose

Antipyretics and analgesics. Used for acute and chronic arthritis, rheumatic pain, neuralgia, low back pain, gout, headache, etc.
