Adding a certain compound to certain chemical reactions, such as: 88625-24-5, name is 5-Chloropyrazine-2-carbaldehyde, belongs to pyrazines compound, 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 88625-24-5, Safety of 5-Chloropyrazine-2-carbaldehyde
A solution of 5-chloropyrazine-2-carbaldehyde (5.20 g, 36.5 mmol) in 50 mL of methanol was cooled to O0C. Sodium borohydride (1.45 g, 38.3 mmol) was added and the reaction mixture was allowed to stir at ambient temperature for 3 hour. Saturated aqueous ammonium chloride (5 mL) was added, and the methanol was removed in vacuo. The resulting residue was dissolved in ethyl acetate (50 mL) and washed with aqueous sodium bicarbonate (2 x 50 mL) and brine (50 mL).
At the same time, in my other blogs, there are other synthetic methods of this type of compound, 5-Chloropyrazine-2-carbaldehyde, and friends who are interested can also refer to it.
