With the rapid development and complex challenges of chemical substances, the synthesis of new drugs is usually one of the most effective ways to increase yield.624-08-8, name is Heptadecan-9-ol, molecular formula is C17H36O, molecular weight is 256.4672, as common compound, the synthetic route is as follows.Computed Properties of C17H36O

9-Heptadecane p-Toluenesulfonate (3): p-toluenesulfonyl chloride (14.7 g, 77 mmol) in CH2Cl2 (60 mL) was added dropwise to a solution of heptadecan-9-ol (2) (18.00 g, 70 mmol) and triethylamine (Et3N) (24.4 mL, 181 mmol) in CH2Cl2 (90 mL) in a dry 250 mL flask. The mixture was stirred for 2 h, 250 mL of water was added, and the mixture was extracted three times with CH2Cl2 (3 * 150 mL). ;The organic phase was washed with water, dried (Na2SO4), and concentrated under reduced pressure. The crude product was purified by silica-gel flash chromatography (cyclohexane-ethyl acetate, 95-5 as eluent) to give 22.5 g of colorless oil, which crystallized as the title product (yield: 78%). 1H NMR (400 MHz, CDCl3): delta (ppm) 7.78 (d, J = 8.3 Hz, 2H), 7.31 (d, J = 8.0 Hz, 2H), 4.54 (p, J = 6.0 Hz, 1H), 2.43 (s, 3H), 1.55 (m, 4H), 1.21 (m, 24H), 0.88 (t, 6H). 13C NMR (101 MHz, CDCl3): delta (ppm) 144.38, 134.97, 129.74, 127.85, 84.78, 70.82, 34.26, 31.97, 29.48, 29.42, 29.28, 24.81, 22.78, 21.71, 14.23. FT-IR (ATR): nu = 2954, 2923, 2852, 1598, 1521, 1495, 1465, 1354, 1305, 1173, 1097, 1020, 895, 816, 766, 720, 662, 575, 554 cm-1.

At the same time, in my other blogs, there are other synthetic methods of this type of compound,624-08-8, Heptadecan-9-ol, and friends who are interested can also refer to it.

Application of 624-08-8, As we all know, there are many different methods for the synthesis of a compound, and people can choose the synthesis method that suits their own laboratory according to the actual situation. 624-08-8, name is Heptadecan-9-ol, molecular formula is C17H36O, The compound is widely used in many fields, so it is necessary to find a new synthetic route. The downstream synthesis method of this compound is introduced below.

From 0 C in a round flask was added the p- toluenesulfonyl chloride (5.5g) and the mixture was stirred and then placed in methylene chloride (150mL). Put Then, hepta-decane-9-ol followed by the addition of (5g) and slowly diluted in methylene chloride (5mL), triethylamine (7mL) and triethylamine hydrochloride (3.71g), and the mixture was stirred for 90 minutes . MC and the organic layer with brineAnd then extracted to remove the remaining water over anhydrous magnesium sulfate, and after evaporation of the solvent was recrystallized from a MC and MeOH to give the Heptadecane-9-yl 4-methlybenzenesulfornate (compound f-4) as a white solid (yield: 64% ).

While traditionally a conservative industry, chemical producers will need to modernize their PR strategies to stay relevant.we look forward to future research findings about 624-08-8, Heptadecan-9-ol.
