Description

4-Fluoro-DL-Phenylalanine is a fluorinated derivative of the essential amino acid phenylalanine, where a fluorine atom is substituted at the para position of the aromatic ring. This structural modification makes it a valuable non-natural amino acid building block for pharmaceutical research and peptide synthesis. It is primarily utilized by researchers and manufacturers in the life sciences sector for developing novel therapeutic agents and biochemical probes.

Application

• Key intermediate in the research and synthesis of novel pharmaceutical compounds and active pharmaceutical ingredients (APIs).
• Building block for the preparation of modified peptides and peptidomimetics in medicinal chemistry.
• Substrate or inhibitor in enzymatic studies and biochemical research.
• Starting material for the development of PET (Positron Emission Tomography) imaging tracers and diagnostic agents.
• Used in agricultural chemical research for creating new compounds with potential biological activity.
• Reference standard in analytical chemistry for method development and quality control.
