Related Products of 2615-15-8, 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. 2615-15-8, name is 3,6,9,12,15-Pentaoxaheptadecane-1,17-diol, molecular formula is C12H26O7, 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.
Preparation of Compound 29a To a solution of hexaethylene glycol (25.0 g, 88.5 mmol) in DCM (100 mL) were added triethylamine (61.7 mL, 443 mmol) and ^-toluenesulfonyl chloride (50.6 g, 266 mmol) at 0 C under N2. After 5 hours at 0 C, the reaction mixture was poured into 1 N aq. HC1 (200 mL) and extracted with DCM (2 x 200 mL). The combined organic layers were washed with saturated aq. NaHCO3 (100 mL) and brine (100 mL), and dried over anhydrous Na2SO4. After filtration and concentration, the residue was purified by column chromatography, which produced the compound 29a (45.0 g, 87 %) as brown oil. 1H- MR (400 MHz, CDC13) delta 7.79 (d, J= 7.6 Hz, 4H), 7.34 (d, J= 7.6 Hz, 4H), 4.16-4.14 (m, 4H), 3.69-3.67 (m, 4H), 3.64-3.56 (m, 16H), 2.44 (s, 6H).
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 2615-15-8, 3,6,9,12,15-Pentaoxaheptadecane-1,17-diol.
