Description

(2S)-2-[[(2S)-2-[[(2S)-1-[(2S)-2-[[(2S,3R)-2-[[(2S)-1-[(2S)-2-[[(2S)-2-amino-3-(4-hydroxyphenyl)propanoyl]amino]-3-hydroxy-propanoyl]pyrrolidine-2-carbonyl]amino]-3-hydroxy-butanoyl]amino]-3-hydroxy-propanoyl]pyrrolidine-2-carbonyl]amino]-3-hydroxy-propanoyl]amino]-3-(4-hydroxyphenyl)propanoic acid is a complex, high-purity synthetic peptide derivative of significant interest in advanced pharmaceutical research and development. This compound matters as a sophisticated building block or intermediate for creating novel therapeutic agents, particularly in the fields of endocrinology and metabolic disease. It is primarily needed by pharmaceutical R&D laboratories, biotech companies, and contract research organizations (CROs) focused on peptide-based drug discovery.

Application

• Pharmaceutical Intermediate: Serves as a critical precursor in the multi-step synthesis of complex peptide-based active pharmaceutical ingredients (APIs).
• Drug Discovery Research: Used as a key scaffold or analog in structure-activity relationship (SAR) studies to develop new therapeutic candidates.
• Peptide Library Synthesis: Employed in the generation of specialized peptide libraries for high-throughput screening against biological targets.
• Biochemical Research: Functions as a tool compound or a standard in analytical method development for peptide characterization (e.g., HPLC, LC-MS).
• Reference Standard: Can be utilized as a high-purity chemical reference standard for quality control and regulatory submissions.

Quality Control

Our (2S)-2-[[(2S)-2-[[(2S)-1-[(2S)-2-[[(2S,3R)-2-[[(2S)-1-[(2S)-2-[[(2S)-2-amino-3-(4-hydroxyphenyl)propanoyl]amino]-3-hydroxy-propanoyl]pyrrolidine-2-carbonyl]amino]-3-hydroxy-butanoyl]amino]-3-hydroxy-propanoyl]pyrrolidine-2-carbonyl]amino]-3-hydroxy-propanoyl]amino]-3-(4-hydroxyphenyl)propanoic acid is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the stringent requirements for pharmaceutical research. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting batch-specific results.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (typically 15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container should be kept in a desiccated environment. For long-term storage, consider conditions of 2-8°C.
