N-Fmoc-N-methyl-2-aminoethanol is a protected amino alcohol widely used as a building block in peptide synthesis. The Fmoc group protects the secondary amine, providing stability during the synthesis process and ensuring protection until the final deprotection step. This compound is particularly valuable in solid-phase peptide synthesis (SPPS), where it facilitates the stepwise assembly of peptides by allowing incorporation of N-methyl ethanolamine units. Additionally, it is employed in the preparation of modified peptides and peptidomimetics, enabling the introduction of specific functional groups or structural modifications. Its application extends to the development of bioactive peptides and pharmaceutical compounds, where precise control over peptide structure is critical.
