With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is 2-bromo-6-methylpyridin-4-amine which has developed particularly rapidly in recent years. Do you know about 2-bromo-6-methylpyridin-4-amine ?
The official answer: 4-amino -2-bromo -6-methylpyridine can be used as an intermediate in organic synthesis. If inhaling 4-amino-2-bromo-6-methylpyridine, move the patient to fresh air; if skin is in contact, remove contaminated clothing, rinse skin with Chemicalbook soap and water, and consult a doctor if feeling unwell; if eye contact occurs, should be separated from the eyelids, with running water or saline rinsing, and immediately medical; if ingestion, immediately Gargle, prohibit emesis, should immediately medical attention.
What’s the application of 2-bromo-6-methylpyridin-4-amine CAS#79055-59-7?
- 4-amino -2-bromo -6-methylpyridine can be used as an intermediate in organic synthesis. Such as the preparation of 2,4-dibromo-6-methylpyridine, the specific steps were as follows: Adding Bromine (2.57 G, 16.2 MMOL) to a solution of 4-amino-2-bromo-6-methylpyridine (1.0 g, 5.4 MMOL) cooled to -10 â ° C in 40% HBR water solution (1.0 ml) and then dissolving the solution of Sodium Nitrite (1.86 g, 27.0 MMOL) in water (3.0 ml) .
- Heat the reaction mixture to room temperature and stir for 3 hours. After that, a saturated Sodium bicarbonate aqueous solution was added and the reaction mixture was extracted with Etoachemicalbookc (2 × 40 ml) .
- The merged organic layer was washed with a saturated sodium thiosulfate aqueous solution (2 × 40mL) and water (2 × 40mL) .
- The organic layer is dried with sodium sulfate, filtered and concentrated. The crude product was purified using a Redisep12g Silica Gel column (0 to 100% ETOAC/HEXANE) to yield 2,4-dibromo-6-methylpyridine, a colorless oily substance.
- XHNMR (300 MHZ, CDCl3) Δ7.49(D, j = 1.2 Hz, 1 h) , 7.28(D, j = 1.2 Hz, 1 h) , 2.51(S, 3 h) .
