Category: 1261269-66-2

Adding a certain compound to certain chemical reactions, such as: 1261269-66-2, 2,4,6-Trichloronicotinaldehyde, can increase the reaction rate and produce products with better performance than those obtained under traditional synthetic methods. Here is a downstream synthesis route of the compound, 1261269-66-2, blongs to pyridine-derivatives compound. HPLC of Formula: C6H2Cl3NO

Ethylhydrazine (2.16 g, 14.39 mmol, 1.00 equiv) was added to a solution of2,4,6-trichloropyridine-3-carbaldehyde (3 g, 14.26 mmol, 1.00 equiv) and triethylamine (4.3 g,42.49 mmol, 3.00 equiv) in ethanol (100 mL) at -78C under nitrogen. The resulting solution was stilTed for 3 hours at 0 C. After completion the reaction was concentrated under vacuum and the residue was purified by a silica gel column eluting with ethyl acetate/petroleum ether (1:20) to give the title compound (800 mg, 26%) as a white solid. LC-MS (ES, m/z): 216 [M+H].

These compound has a wide range of applications. It is believed that with the continuous development of the source of the synthetic route,1261269-66-2, its application will become more common.
