BOC-GLY-OME is widely used in peptide synthesis as a protecting group for amino acids. It helps in the selective protection of the amino group during the formation of peptide bonds, ensuring that reactions occur at the desired sites without interference. This compound is particularly valuable in solid-phase peptide synthesis (SPPS), where it aids in the stepwise construction of peptides. Additionally, it is employed in the preparation of glycine derivatives, which are essential intermediates in the production of various pharmaceuticals and bioactive peptides. Its stability under reaction conditions and ease of removal make it a preferred choice in organic and medicinal chemistry research.
