Application of 40876-98-0, Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 40876-98-0, name is Sodium 1,4-diethoxy-1,4-dioxobut-2-en-2-olate, This compound has unique chemical properties. The synthetic route is as follows.
[0713] Step 2: Synthesis of ethyl 6-hydroxy-lH-pyrazolo[3,4-b]pyridine-4-carboxylate [0714] A stirred solution of lH-pyrazol-3 -amine (45 g, 542 mmol) in acetic acid (297 mL) and water (900 mL) was cooled to 0 C and diethyl oxaloacetate sodium salt (1 13.85 g:542.16 mmol) was added to it. Resulting solution was heated at 100 C for overnight. After completion of reaction, solid was filtered and dried to obtain the desired intermediate (25 g, 22%).
The chemical industry reduces the impact on the environment during synthesis Sodium 1,4-diethoxy-1,4-dioxobut-2-en-2-olate. I believe this compound will play a more active role in future production and life.
