Description

Pth-Dl-Aspartic Acid CAS NO 31364-98-4 is a protected derivative of the amino acid aspartic acid, where the amine group is shielded by a phthaloyl (Pth) group. This modification is critical for enabling selective peptide synthesis and advanced organic transformations, ensuring reaction fidelity in complex molecular assembly. It serves as a key chiral building block and intermediate for researchers and manufacturers in the pharmaceutical, biotechnology, and fine chemical sectors who require high-purity, specialized reagents.

Application

• Peptide Synthesis Intermediate: Used as a protected amino acid derivative in solid-phase and solution-phase peptide synthesis to prevent unwanted side reactions.
• Pharmaceutical Research: Serves as a crucial building block in the development and production of active pharmaceutical ingredients (APIs) and drug candidates.
• Biochemical Research: Employed in the study of enzyme mechanisms, protein structure, and metabolic pathways as a specialized reagent.
• Fine Chemical Synthesis: Acts as a chiral precursor or intermediate in the synthesis of complex organic molecules, flavors, and fragrances.
• Asymmetric Catalysis: Utilized in the preparation of chiral ligands or catalysts for stereoselective chemical reactions.
