Chemistry graduates have much scope to use their knowledge in a range of research sectors, including roles within chemical engineering, chemical and related industries, healthcare and more.21905-86-2. Introduce a common compound, CAS is 21905-86-2, Name is Cinnoline-4-carboxylic acid, belongs to cinnolinecompound.
EXAMPLE 2 Potassium Cinnoline-4-carboxylate (2) 5.10 g of (1) was added over 30 minutes to a vigorously stirred solution of 2.02 g of potassium carbonate in 25 ml of water, at room temperature. The resulting mixture was stirred for one hour at room temperature, then treated with charcoal, and after filtration the water was evaporated. The residue was azeotropically distilled with toluene and dried at 70 C. under reduced pressure, to give 2, as a light tan powder, m.p.: above 280 C.
The result showed that such a combination of chemo- and biocatalysis improved the catalytic yield more than two times compared with that of sole metal catalysis.I hope my blog about Cinnoline-4-carboxylic acid is helpful to your research.21905-86-2
