用途: PEG3-Tos is a PEG derivative containing a hydroxyl group and a tosyl group. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. The tosyl group is a very good leaving group for nucleophilic substitution reactions. 物理化学性质: CAS号:77544-68-4 常用中文名:对甲苯磺酸酯-三聚乙二醇 常用英文名:Tos-PEG3 分子式:C13H20O6S 分子量:304.35900 密度:1.234±0.06 g/cm3 沸点:460.0±35.0 °C 熔点:N/A 闪点:N/A 储存条件:2-8°C,保存于惰性气体中 |
