Description

Boc-Cck 33 CAS NO 35150-06-2 is a protected peptide derivative, specifically a Boc-protected cholecystokinin fragment, widely used as a critical building block in advanced pharmaceutical research and peptide synthesis. This high-purity intermediate is essential for ensuring the precise construction and biological activity of complex peptide-based drug candidates. It is primarily required by research institutions, pharmaceutical R&D departments, and fine chemical manufacturers focused on developing therapeutics for neurological and gastrointestinal disorders.

Application

• Pharmaceutical Intermediate: A key precursor in the solid-phase and solution-phase synthesis of cholecystokinin (CCK) analogs and related peptide hormones.
• Neuroscience Research: Used in the development of receptor ligands and probes to study CCK receptor subtypes (CCKA and CCKB) in the central and peripheral nervous systems.
• Drug Discovery: Serves as a crucial scaffold for creating potential therapeutics targeting anxiety, panic disorders, satiety, and pancreatic functions.
• Bioconjugation: Employed in the preparation of peptide conjugates for diagnostic imaging or targeted drug delivery systems.
• Academic & Contract Research: Utilized in university laboratories and CROs (Contract Research Organizations) for fundamental peptide chemistry and medicinal chemistry projects.

Quality Control

Every batch of Boc-Cck 33 is manufactured under strict quality management systems and undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide full traceability and a Certificate of Analysis (COA) with each shipment, detailing key parameters such as assay, chiral purity, and impurity profiles. Our quality commitment aligns with the standards expected for pharmaceutical-grade intermediates used in GMP (Good Manufacturing Practice) environments.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a freezer. This product is hygroscopic (moisture-sensitive) and should be handled under anhydrous conditions. Allow the sealed container to equilibrate to room temperature before opening to prevent condensation and moisture ingress.
