N-ALPHA-(9-FLUORENYLMETHOXYCARBONYL)-D-ASPARAGINE - Introduction
Fmoc-D-asparagine is an organic compound, which is composed of Fmoc protecting group, D-asparagine and a certain number of reactants. Its structural formula is: Fmoc-D-asparagine.
Fmoc-D-asparagine is a commonly used amino acid protection reagent, mainly used in the synthesis of peptides and proteins. By protecting the α-amino group in the peptide synthesis reaction, their non-specific reaction can be avoided. In addition, it also has the advantages of helping location synthesis, improving yield, purification and reducing side reactions.
The preparation of Fmoc-D-asparagine is generally obtained by reacting D-asparagine with an Fmoc compound in an organic solvent, reacting and purifying through a series of steps. It should be noted that the preparation process needs to be carried out under an inert atmosphere to avoid reaction with moisture and oxygen in the air.
Regarding safety information, Fmoc-D-asparagine is a chemical and needs to be paid attention to during use and storage. Avoid direct contact with skin and eyes. Wear protective gloves and goggles when using. In addition, it should be operated in a well-ventilated laboratory environment and stored in a dry, dark place, away from heat and flammable materials. In the event of any accident, immediately rinse the affected area with plenty of water and seek medical attention immediately.
