10-Bromo-1-decanol is used as an important raw material and intermediate used in organic Synthesis, pharmaceuticals, agrochemicals and dyestuff.

ChEBI: 10-Bromo-1-decanol is a primary alcohol.

General procedure for the synthesis of 10-bromo-1-decanol from 1,10-decanediol: 1,10-decanediol (10 g, 57.47 mmol) was dissolved in toluene (600 mL) and transferred to a 1 L two-necked, round-bottomed flask fitted with a Dean-Stark separator. 48% hydrobromic acid (7.15 mL, 63.21 mmol) was slowly added to the reaction system and subsequently heated to reflux for 16 hours. After completion of the reaction, it was cooled to room temperature and the reaction mixture was washed sequentially with 1 N hydrochloric acid, 2 M aqueous sodium hydroxide, deionized water and saturated saline. The organic phase was separated, dried with anhydrous sodium sulfate, filtered and concentrated under reduced pressure. The crude product was purified by silica gel column chromatography (eluent: 15% ethyl acetate/hexane) to afford 10-bromo-1-decanol as a colorless transparent oil (12.7 g, 93% yield). Thin layer chromatography (TLC) Rf = 0.45 (unfolding agent: 20% ethyl acetate/hexane); 1H NMR (500 MHz, CDCl3): δ 3.63 (t, J = 5.8 Hz, 2H), 3.39 (t, J = 6.8 Hz, 2H), 1.85 (m, 2H), 1.56 (m, 2H), 1.42 (m, 2H), 1.38- 1.27 (m, 10H); 13C NMR (125 MHz, CDCl3): δ 62.9, 33.9, 32.7, 32.6, 29.3, 29.2, 29.2, 28.6, 28.0, 25.6; infrared spectra (neat sample): νmax 2927, 2856, 1738, 1593, 1449, 1367, 1241 cm-1; high-resolution mass spectrum (ESI): calculated value C10H22BrO [M + H]+ 237.0854, measured value 237.0845.
