Application of 84547-87-5, In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 84547-87-5 as follows.
(c) 3,8-Dichlorodipyrazolo[T .5-a; 1 ‘,5’-d]pyrazine-4,9-dior.eA mixture of 4-chloropyrazole-3-carboxylic acid (2.0 mmol, 300 mg; see step (b) above) in tbionyl chloride (25 mL) was heated at reflux for 3 days. The excess thionyl chloride was removed in vacuo and the crude product employed in the next step without purification.
According to the analysis of related databases, 84547-87-5, the application of this compound in the production field has become more and more popular.
