Colorless Slightly Yellow Clear Liquid. | [Uses]
2-Azidoethanol is used as a reagent in the glycosylation of mono- or polysaccharides. 2-Azidoethanol is also used as a 2’-deoxy-ethynyluridine (EdU) blocker in nuclear DNA, preventing cross reactivity with other antibodies in order to better study its related pathways in the body. | [Preparation]
2-Azidoethanol synthesis: Sodium azide (14.6 g, 224 mmol, 1.5 eq.) was added portion wise to a stirred mixture of 2- chloroethanol (12.0 g, 149 mmol, 1 eq.) in H2O (80 mL) at 0°C. The reaction mixture was slowly warmed up to room temperature and stirred for another 4 h. Additional sodium azide (9.71 g, 149 mmol, 1 eq.) was added and the solution was heated under reflux at 80°C overnight. After completion, the mixture was extracted with Et2O (3×50 mL) and the combined organic phases were washed with Brine (1× 10 mL) and dried over MgSO4. The solvent was removed in vacuo to yield a colorless oil (10.57 g, 121.4 mmol, 81%).
