Reference of 123-32-0, The chemical industry reduces the impact on the environment during synthesis 123-32-0, name is 2,5-Dimethylpyrazine, I believe this compound will play a more active role in future production and life.
BDPEP laser dye was prepared as follows (Scheme 1); Indimethyl formamide (DMF), a mixture from 2,5-dimethylpyrazine(0.5 g) and 4-(dimethylamino) benzaldhyde (2.3 g) is dissolved.Then, this mixture is cooled to 0 C. A small amount of potassiumtri-butanolate (1.55 g) was added to this mixture while stirringuntil all the raw materials were dissolved. Distilled water changedto introduce after the reaction was completed, and the productturned into isolated with chloroform. The color of the productobtained is red solid (1.4 g, 52%). The structure of the product obtainedis characterized by IR, 1H NMR and 13C NMR [15].1H NMR (CDCl3, 600 MHz): d 3.03 (s, 12H), 6.74 (d,4H,J 8.9 Hz), 6.94 (d,2H,J 16.1 Hz), 7.49 (d, 4H, J 8.9 Hz), 7.64 (d,2H, J 16.1 Hz), 8.49 (s, 2H). 13C NMR (CDCl3, 150 MHz): d 40.3,112.2, 120.7, 127.5, 132.8, 141.7, 148.0, 150.7.
In the field of chemistry, the synthetic routes of compounds are constantly being developed and updated. I will also mention this compound in other articles, 2,5-Dimethylpyrazine, other downstream synthetic routes, hurry up and to see.
