产品详情(用途,包装等)
用途: Hydroxy-PEG8-acid is a PEG derivative containing a hydroxyl group with a terminal carboxylic acid. The terminal carboxylic acid can be reacted with primary amine groups in the presence of activators (e.g. EDC, or DCC) to form a stable amide bond. The hydrophilic PEG spacer increases solubility in aqueous media. The hydroxyl group enables further derivatization or replacement with other reactive functional groups. 物理化学性质: CAS号:937188-60-8 常用中文名:HO-PEG8-CH2CH2COOH 常用英文名:HO-PEG8-CH2CH2COOH 分子式:C19H38O11 分子量:442.49800 密度:1.148±0.06 g/cm3 (20 °C, 760 mmHg) 沸点:554.3±50.0 °C (760 mmHg) 熔点:N/A 闪点:N/A 储存条件:-20°C,干燥,密封 |
