Description

(2S)-N-[(1S)-1-[[(2R)-1-[(2S)-2-[[(1S)-4-amino-1-(carbamoylmethylcarbamoyl)butyl]carbamoyl]pyrrolidin-1-yl]-1-oxo-3-sulfanyl-propan-2-yl]carbamoyl]-2-carbamoyl-ethyl]-2-[[(2S,3S)-2-[[(2S)-2-[[(2R)-2-amino-3-sulfanylidene-propanoyl]amino]-3-phenyl-propanoyl]amino]-3-methyl-pentanoyl]amino]pentanediamide is a complex, stereochemically-defined peptide derivative of significant interest in advanced pharmaceutical research and development. This compound is valued for its potential role as a key intermediate or active pharmaceutical ingredient (API) in the synthesis of novel therapeutic agents, particularly those targeting specific enzymatic pathways or protein-protein interactions. It is primarily utilized by research institutions, pharmaceutical R&D laboratories, and fine chemical manufacturers engaged in the development of peptide-based drugs and high-value biochemicals.

Application

• Pharmaceutical Intermediate: Serves as a critical building block in the multi-step synthesis of novel peptide therapeutics and investigational new drugs (INDs).
• Biochemical Research: Used as a reference standard or a substrate in enzymatic studies, proteomics research, and structure-activity relationship (SAR) investigations.
• Preclinical Development: Employed in the formulation and testing of potential drug candidates during early-stage pharmacological and toxicological studies.
• Custom Peptide Synthesis: A key component for contract research organizations (CROs) and CDMOs specializing in the production of complex, non-standard amino acid sequences.
• Protease Inhibitor Development: Due to its structural features, it may be investigated for applications in designing inhibitors for specific proteases.
• Academic Research: Utilized in university laboratories for advanced studies in organic chemistry, medicinal chemistry, and peptide science.

Quality Control

This high-purity biochemical is manufactured under strict quality control protocols suitable for research and pharmaceutical applications. Each batch is characterized using advanced analytical techniques including HPLC, MS, and NMR to confirm identity, chiral purity, and chemical composition. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to ensure traceability and support your regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) or as specified on the label. This material is hygroscopic (moisture-sensitive) and easily oxidized; it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep the container in a dry, cool, and well-ventilated area.
