产品说明 应用 DL-asparagine is a racemic mixture of the non-essential amino acids, L and D-aparagine. It is generally used in growth-media for bacteria-growth. DL-Asparagine monohydrate can also be used to synthesize other salts such as DL-asparaginium perchlorate, DL-asparaginium nitrate and dimethyl DL-aspartate. 包装 100, 500 g in glass bottle 基本信息 | 线性分子式 | NH2COCH2CH(NH2)COOH · H2O | | 分子量 | 150.13 | | Beilstein | 1723525 | | EC 号 | 221-521-1 | | MDL编号 | MFCD00151039 | | PubChem化学物质编号 | 57646890 | | NACRES | NA.22 |
