Researchers who often do experiments know that organic synthesis is a process of preparing more complex target molecules from simple raw materials through one or more chemical reactions. Generally, it requires fewer steps, and cheap raw materials. 5521-55-1, name is 5-Methylpyrazine-2-carboxylic acid, A new synthetic method of this compound is introduced below., Product Details of 5521-55-1
A mixture of 5-methyl-2-pyrazinecarboxylic acid (1) (0.01 mol) and hydrazine hydrate (0.025 mol) in ethanol (20 mL) was refluxed for 9 h on consistent stirring. After completion of the reaction (monitored by the TLC), the reaction mixture is cooled to room temperature, poured in ice-cold water (20 mL). Thus the solid separated was filtered off and the crude product was recrystallized from ethyl acetate to give pure 5-methyl-2-pyrazinecarboxylic acid hydrazide (2).
The synthetic route of 5521-55-1 has been constantly updated, and we look forward to future research findings.
