Research speed reading in 2021. We’ll be discussing some of the latest developments in chemical about CAS: 40253-47-2, name is Ethyl 5-methyl-1H-1,2,4-triazole-3-carboxylate belongs to triazoles compound, it is a common compound, a new synthetic route is introduced below. COA of Formula: C6H9N3O2
A mixture of ethyl 5-methyl-lH-l ,2,4-triazole-3-carboxylate (1.0 g, 6.45 mmol) and sodium hydroxide (1.702 mL, 32.2 mmol) in tetrahydrofuran (30 mL) was stirred at ambient temperature for 16 hours. Volatiles were removed, and the residue was acidified with 1 N HQ solution. Water was removed under high vacuum, and the crude residue was purified by HPLC (0-70% acetonitrile in 0.1 % trifluoroacetic acid/water on Phenomenex C18 10 mupiiota (250 mm x 50 mm) column at a flowrate of 50 mL/minute) to give 460 mg of the title compound as a white solid.
In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to serve as an indispensable tool to navigate research efforts intended to model. Read on for other articles about 40253-47-2.
