N-ALPHA-FMOC-L-METHIONINE - Reference Information
| Introduction | Fmoc-L-methionine, FMOC-L-Methionine in English, is an intermediate in bio-organic synthesis, the appearance was white crystalline powder at normal temperature and pressure. Preservation method: Store in a sealed container, and put in a cool, dry place. The place of storage must be kept away from the oxidizing agent. |
| Use | Fmoc-L-methionine is commonly used in biochemistry, especially in the synthesis of polypeptides. In addition, Fmoc-L-methionine is an amino acid having an isoelectric point, which requires careful pH adjustment of the reaction system to achieve the desired product form. |
| synthetic route | for the synthesis of Fmoc-L-methionine, the most commonly used is the molecular fragment coupling condensation reaction, first, the desired target product is obtained by a simple condensation reaction in one step by synthesizing the fragment of the corresponding structure. Of course, the molecular fragment may also need to be prepared through many steps. For example, in the reaction shown in the following figure, Fmoc-L-methionine is obtained by a simple amidation reaction in one step. |
