基本信息
| Linear Formula【线性分子式】 | NH2C(CH2OH)3 · HCl |
| Molecular weight | 157.60 |
| Beilstein | 3675235 |
| MDL number | MFCD00012590 |
| General description【一般描述】 | Absorbance (1.0 M, H2O, 260 nm):≤0.1. Widely used as a biological buffer (absorbance: <0.1 at 260 nm, 1.0 M, H2O). A 1.0 M solution in H2O has a pH range of 3.5-5.0 and a pKa of 8.3 at 20°C. Useful in the pH range of 7.0-9.0. Has a pKa of 8.1 at 25°C. |
| Application【应用】 | 所有缓冲液的pH值都与温度和浓度有关。对于Tris缓冲液，降温每℃其pH值约增加0.03单位，每10倍稀释其pH降低0.03-0.05单位。 对于精确的应用，请使用带有玻璃/甘汞组合电极并仔细校准过的pH计。 |
