Each compound has different characteristics, and only by selecting the characteristics of the compound suitable for a specific situation can the compound be applied on a large scale. 126-38-5, name is 1-Bromo-2,2-dimethoxypropane, This compound has unique chemical properties. The synthetic route is as follows., SDS of cas: 126-38-5

2-aminc-5-brcmcpyrazine (lOg, 57mmcl) and 1-brcmc-2,2-dimethcxy-prcpane (15 g) were dissolved in IPA (30 mL) and heated at 100 00 in a sealed tube for 3 days. The reactionwas quenched with sodium bicarbonate solution and filtered and extracted with ethyl acetate;the organic layer was dried over sodium sulphate and concentrated to give a brown solid that was used for the next step without further purification.

According to the analysis of related databases, 126-38-5, the application of this compound in the production field has become more and more popular.

A common compound: 126-38-5, name is 1-Bromo-2,2-dimethoxypropane, belongs to ethers-buliding-blocks compound, it can change the direction of chemical reaction, and react with certain compounds to generate new functional products. A new synthetic method of this compound is introduced below. 126-38-5

To a mixture of 3-bromobenzenethiol (8.7 g, 46 mmol) and l -bromo-2,2- dimethoxypropane (8.4 g, 46 mmol) in NN-dimethylformamide (50 mL) was added potassium carbonate (9.5 g, 69 mmol) at room temperature. The mixture was stirred at 80 C overnight. On completion, the reaction mixture was quenched with water and extracted with ethyl acetate (3 x 100 mL). The combined organic layers were washed with water and brine, dried over anhydrous sodium sulfate and concentrated in vacuo to give crude compound B-287 (13 g, 97% yield) as a colorless oil.

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, 126-38-5, other downstream synthetic routes, hurry up and to see.

In the chemical reaction process, reaction time, type of solvent, can easily affect the result of the reaction, thereby determining the yield and properties of the reaction product. An updated downstream synthesis route of 126-38-5 as follows. 126-38-5

To a solution of 4-bromopyridin-2-amine (1.08 g, 6.24 mmol) in H20 (20 mL) were added l-bromo-2,2-dimethoxypropane (5.59 g, 30.5 mmol) and 4-methylbenzenesulfonic acid (209.4 mg, 1.216 mmol). The reaction mixture was heated to reflux and stirred for 12 hours and then adjusted to pH = 10 with saturated Na2C03 aqueous solution, the resulting mixture was extracted with EtOAc (100 mL x 3). The combined organic layers were dried over anhydrous Na2S04, filtered and concentrated in vacuo. The residue was purified by silica gel column chromatography (PE/EtOAc(v/v) = 3/1) to give the title compound as a yellow solid (750 mg, yield 57%).MS (ESI, pos. ion) m/z: 211.1 [M+H]+.

According to the analysis of related databases, 126-38-5, the application of this compound in the production field has become more and more popular.
