Z-L-Aspartic Acid Dibenzyl Ester

Product Overview

Z-L-Aspartic Acid Dibenzyl Ester, frequently recognized by its chemical abbreviation Cbz-Asp(OBzl)-OBzl, stands as a critical protected amino acid derivative within the realm of advanced pharmaceutical synthesis. This compound features a dual protection strategy, utilizing the benzyloxycarbonyl (Cbz or Z) group on the alpha-amino function and benzyl ester groups on the carboxylic acid side chains. Such structural configuration is essential for preventing unwanted side reactions during complex peptide chain assembly. Our manufacturing process ensures that every batch meets stringent quality benchmarks, making it an ideal choice for research laboratories and large-scale production facilities alike.

As a fundamental building block, this material facilitates the precise construction of biologically active peptides. The stability of the protecting groups allows chemists to perform multiple coupling steps without compromising the integrity of the aspartic acid residue. We prioritize consistency and reliability, providing a product that supports high-yield synthesis routes while minimizing purification challenges downstream.

Technical Specifications

Our quality control team rigorously tests each production lot to verify compliance with international chemical standards. The following table outlines the key physical and chemical properties associated with this product.

Applications in Peptide Chemistry

This protected amino acid is primarily utilized in the solid-phase and solution-phase synthesis of peptides containing aspartic acid residues. The benzyl ester protection is particularly valuable because it remains stable under many conditions that might affect other functional groups, yet can be removed selectively when required. This versatility makes it a preferred reagent for creating therapeutic peptides, diagnostic agents, and custom research compounds.

• Effective for multi-step peptide synthesis protocols.
• Compatible with various coupling reagents and activation methods.
• Suitable for producing pharmaceutical intermediates requiring high stereochemical purity.
• Ideal for academic research and industrial scale-up projects.

Quality Assurance and Storage

We understand that the success of your synthesis depends on the quality of your starting materials. Therefore, our facility operates under strict quality management systems. Each drum is accompanied by a Certificate of Analysis (COA) detailing the specific test results for that batch. To maintain optimal stability, we recommend storing the product in a cool, dry environment between 0 to 5 degrees Celsius. Ensure the container remains tightly closed to prevent moisture absorption, which could affect the purity over time. Proper handling and storage guarantee that the material retains its specified characteristics throughout its shelf life.
