The major producers of chemicals have been the Europe, Japan and China. Due to the growing call for a cleaner, greener environment, people will have to find innovative ways to maintain their relevance. Here is a compound 70165-31-0, name is 6-Cyanonicotinic acid. This compound has unique chemical properties. The synthetic route is as follows. SDS of cas: 70165-31-0
EXAMPLE 1 5-Carboxy-2-(4,5-dihydro-2-thiazolyl)-pyridine Sodium (11 mmol) is added to a flask containing 75 ml of ethanol. As soon as the sodium has dissolved, 10 mmol of 5-carboxy-2-cyanopyridine and 11 mmol of 2-amino-ethanethiol are added and the solution is refluxed for 24 h. The solution is then diluted with 25 ml of water, made acidic (pH=5) with 2N HCl and evaporated. The residue is dissolved in 100 ml of hot chloroform, the salts are filtered off and the filtrate on cooling gives crystals of the title compound, m.p. 234-235 C. The starting material is prepared as follows:
With the rapid development of chemical substances, we look forward to future research findings about 70165-31-0.
