Chemical properties: yellow to orange crystals. Melting point 215-217 ℃. Water decomposition. Soluble in benzene, acetic acid, slightly soluble in chloroform and methylene chloride.

Usage:
1. Synthesis of oxidant steroids for birth control medication chlormadinone Gestrinone production.
2 is an excellent dehydrogenation agent, mainly used for the synthesis of steroid drugs with a number of advanced synthesis spices dehydrogenation.
3. For the efficient synthesis of 12- and Ph3P benzisoxazole compounds; a variety of compounds (such as sulfur acetals, acetals and ketals) General deprotecting agent; for imine and alkene or alkyne electron transfer agents of quinoline
4. For pharmaceutical intermediates, specifically as steroid hormone compounds dehydrogenating agent

Brief manufacture process:

2,3-dicyano-hydroquinone hydrochloride and slurried at about 35 ℃ 70% nitric acid was added slowly, stirring continued reaction 1h. Filtered, washed with carbon tetrachloride and dried to give DDQ, 90% yield.
