Product name:2,3-Dichloro-5,6-dicyano-1,4-benzoquinone Synonyms:1,2-Dichloro-4,5-Dicyanobenzoquinone;2,3,5,6-Dichlorodicyanoquinone;2,3-dichloro-5,6-dicyano-4-benzoquinone;2,3-Dichloro-5,6-dicyano-para-benzoquinone;2-dicarbonitrile,4,5-dichloro-3,6-dioxo-4-cyclohexadiene-1;4-Cyclohexadiene-1,2-dicarbonitrile,4,5-dichloro-3,6-dioxo-1;Dichlorodicyanobenzoquinone;Dichlorodicyano-p-benzoquinone CAS:84-58-2 Formula:C8Cl2N2O2 Molecular weight:227 EINECS:201-542-2 Melting point:210-215 °C (dec.)(lit.) Storage:0-6°C Water solubility:reacts Sensitivity:Moisture Sensitive Merck:14,3063 BRN:747939 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.
