Product Usage

Peptide synthesis core monomer: Classic Boc-protected amino acid building block for solid-phase & liquid-phase peptide synthesis, widely used to introduce L-leucine residue into polypeptide chains; Boc group can be deprotected via acidolysis (TFA/HCl) to expose free amino group.
Pharmaceutical intermediate: Raw material for synthetic APIs, anti-tumor peptides, hormone analogues and enzyme inhibitor drug development.
Biochemical reagent: High-purity grade as reference standard for amino acid chromatographic quantification in lab analysis.
Custom fine chemical: Precursor for chiral catalyst and amino acid derivative derivatization synthesis.
