Description

L-Threoninamide, N-[2-[4-(2-hydroxyethyl)-1-piperazinyl]acetyl]-D-phenylalanyl-L-cysteinyl-L-tyrosyl-D-tryptophyl-L-lysyl-(2S)-2-aminobutanoyl-L-cysteinyl-, cyclic (2→7)-disulfide is a complex, synthetic peptide derivative featuring a cyclic disulfide bridge, which is critical for its structural stability and biological activity. This compound is of significant interest for advanced research and development in the pharmaceutical and biotechnology sectors, particularly in the study of peptide-based therapeutics and hormone analogs. It is primarily utilized by research institutions, pharmaceutical R&D departments, and specialty chemical manufacturers focused on developing novel drug candidates, diagnostic tools, and biochemical probes.

Application

• Pharmaceutical Research & Development: Serves as a key intermediate or reference standard in the synthesis and study of novel peptide-based drug candidates, particularly those targeting hormone receptors.
• Biochemical Research: Used as a high-purity biochemical tool in academic and industrial laboratories to investigate peptide structure-activity relationships (SAR), receptor binding studies, and signal transduction pathways.
• Reference Standard: Employed as a certified reference material (CRM) in analytical laboratories for method development, validation, and quality control of related peptide substances.
• Preclinical Studies: Utilized in in vitro and in vivo studies to evaluate the pharmacokinetics, metabolism, and efficacy of peptide analogs in therapeutic models.
• Specialty Synthesis: Acts as a sophisticated building block for the custom synthesis of more complex peptide conjugates or for labeling with isotopes or fluorescent tags for diagnostic applications.

Quality Control

Our L-Threoninamide derivative is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, mass spectrometry (MS) for identity confirmation, and amino acid analysis (AAA). We provide a detailed Certificate of Analysis (COA) with every shipment, which includes batch-specific results for identity, purity, and related substances. Production can be aligned with cGMP guidelines for advanced research and pre-clinical applications upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below for long-term stability. This product is hygroscopic (moisture-sensitive); allow the sealed vial to equilibrate to room temperature before opening to minimize moisture uptake. For extended storage, consider under an inert atmosphere.
