"Fmoc-D-Tyr(tBu)-OH | CAS 118488-18-9 | Fmoc-D-Tyrosine (O-T-Butyl) is an amino acid derivative and can be used as a biochemical reagent. also widely used in the research of peptide drugs, food and pesticide fields. Fmoc-D-Tyr(tBu)-OH is an Fmoc protected tyrosine derivative that is potentially useful for proteomics studies and solid phase peptide synthesis techniques. Tyrosine is a very important amino acid - one of the few amino acids which is phosphorylated to vary the physical properties of the peptides, and is a precursor for the formation of iodinated thyroid hormones. The Fmoc group is typically removed with a base such as pyridine - an orthogonal de-protection strategy to the acid labilie Boc group."
