Description

Z-Phe-Gly-Phe-Gly-Oh is a synthetic, protected peptide sequence featuring a benzyloxycarbonyl (Z) protecting group. This compound serves as a crucial building block (intermediate) in solid-phase peptide synthesis (SPPS), enabling the controlled elongation of peptide chains. It is primarily utilized by research institutions and pharmaceutical developers working on novel therapeutic peptides, diagnostic agents, and biochemical tools. The product is supplied as a high-purity intermediate to ensure consistent results in downstream synthesis applications.

Application

• Pharmaceutical Intermediate: Key building block for the research and development of novel therapeutic peptide drugs.
• Biochemical Research: Used as a standard or reagent in studies of peptide structure, function, and metabolism.
• Solid-Phase Peptide Synthesis (SPPS): A protected dipeptide fragment for the efficient, sequential construction of longer, complex peptide sequences.
• Protease Substrate Analog: Potential use in the design and testing of enzyme inhibitors for proteases that cleave at phenylalanine-glycine bonds.
• Material Science: Intermediate for creating peptide-based polymers or biomaterials with specific functional properties.

Quality Control

Our Z-Phe-Gly-Phe-Gly-Oh is manufactured under controlled conditions to ensure high chemical purity and batch-to-batch consistency, suitable for research and development applications. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. While produced with research-grade standards, specifications can be aligned with customer-specific requirements for advanced applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed after each use to minimize exposure to atmospheric humidity. For long-term storage, consider desiccants or inert atmosphere.
