504-02-9 - Application:

1,3-Cyclohexanedione (CAS: 504-02-9), is a cyclohexanedione carrying oxo substituents at positions 1 and 3. It is a beta-diketone and a cyclohexanedione.
HPLC Labeling Reagents. Effect test of HPLC derivatization Effective as labeling agent for Formaldehyde, Acetaldehyde, Propionaldehyde, n-Butyraldehyde, n-Valeraldehyde
Used as a pharmaceutical intermediate; used in organic synthesis.
1,3-Cyclohexanedione can be used as an intermediate of Carvedilol (CAS: 72956-09-3)
1,3-Cyclohexanedione is the intermediate of herbicides sulcotrione and nitrosulfonone. 1,3-Cyclohexanedione is also Nitisinone intermediate.

504-02-9 - Production Method:

The preparation method is to use resorcinol to carry out hydrogenation reaction in the presence of Raney nickel catalyst to obtain the product. Put resorcinol and sodium hydroxide solution into a autoclave, add nickel catalyst, and react with hydrogen at 50℃, 70-100 atmosphere for 10-12h. Then the temperature is lowered, the pressure is relieved, the catalyst is filtered out, the filtrate is acidified with concentrated hydrochloric acid, cooled to 0℃, and the crystals are filtered out, that is, crude 1,3-Cyclohexanedione. The crude product is recrystallized with hot benzene to obtain the finished product.
