Description

Depreotide CAS NO 161982-62-3 is a synthetic peptide somatostatin analog, specifically designed for high-affinity binding to somatostatin receptor subtypes. This compound is of significant value in the field of nuclear medicine and diagnostic imaging as a key precursor for radiolabeling. It serves as a critical component for researchers and pharmaceutical developers working on targeted diagnostic agents. Its primary utility is in the development of radiopharmaceuticals for the detection and localization of neuroendocrine tumors and other somatostatin receptor-positive tissues.

Application

• Radiopharmaceutical Precursor: Primary use as a starting material for the synthesis of Technetium-99m (99mTc) labeled diagnostic agents, such as 99mTc-Depreotide.
• Oncology Diagnostics: Key component in imaging kits used for Single Photon Emission Computed Tomography (SPECT) to visualize and stage somatostatin receptor-expressing tumors, including certain lung cancers and neuroendocrine tumors.
• Research & Development: Essential tool in biomedical research for studying somatostatin receptor distribution, function, and for the preclinical evaluation of new diagnostic and therapeutic compounds.
• Molecular Imaging Probe Development: Used in the development of novel peptide-based probes for targeted molecular imaging applications.
• Quality Control Reference Standard: Serves as a high-purity reference standard in the quality control and validation of commercial diagnostic imaging kits.

Quality Control

Our Depreotide is manufactured under strict quality systems to ensure it meets the exacting standards required for pharmaceutical and diagnostic applications. Each batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation, and is supplied with a detailed Certificate of Analysis (COA). We adhere to relevant GMP guidelines for active pharmaceutical ingredients (APIs) to guarantee consistency, traceability, and reliability for your critical research and production needs.

Storage

Preserve in a tightly closed container, protected from light. Store at -20°C or below in a dedicated freezer. This product is hygroscopic (moisture-sensitive); allow the vial to equilibrate to room temperature in a dry environment before opening to prevent condensation and moisture uptake. For long-term storage, consider under an inert atmosphere.
