Description

D-4-Isopropylphenylalanine CAS NO 755724-85-7 is a high-purity, non-natural amino acid derivative featuring an isopropyl-substituted phenyl ring. This chiral building block is critical for the synthesis of complex peptides and pharmaceutical intermediates where precise stereochemistry and specific lipophilic character are required. It is primarily utilized by research institutions and manufacturers in the pharmaceutical, biotechnology, and advanced material science sectors for developing novel active pharmaceutical ingredients (APIs) and specialty biochemicals.

Application

• Pharmaceutical Intermediate: A key chiral synthon in the research and development of novel therapeutic peptides and small molecule drugs.
• Peptide Synthesis: Used in solid-phase and solution-phase peptide synthesis to incorporate a hydrophobic, sterically defined side chain.
• Proteomics Research: Serves as a modified amino acid residue in the study of protein structure, function, and protein-protein interactions.
• Chemical Biology Tool: Employed in the design and synthesis of enzyme inhibitors, receptor ligands, and molecular probes.
• Material Science: Potential building block for advanced polymers and functional organic materials requiring specific aromatic and chiral motifs.

Quality Control

Our D-4-Isopropylphenylalanine is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including chiral purity verification by HPLC, to ensure it meets the high standards required for pharmaceutical research and development. Certificates of Analysis (COA) detailing identity, purity, and specific impurity profiles are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent moisture absorption.
