Description

Benzamidine CAS NO 618-39-3 is a potent and selective competitive inhibitor of serine proteases, such as trypsin and trypsin-like enzymes. This small molecule organic compound is a critical biochemical tool and a key building block in pharmaceutical research and development. It is essential for researchers and manufacturers in the life sciences, biotechnology, and pharmaceutical industries who require high-purity enzyme inhibitors for diagnostic applications, proteomics, and drug discovery.

Application

• Biochemical Research & Proteomics: A fundamental tool for studying serine protease mechanisms, enzyme kinetics, and protein-protein interactions in vitro.
• Pharmaceutical Intermediate: Serves as a crucial synthetic precursor for more complex protease inhibitors and active pharmaceutical ingredients (APIs).
• Diagnostic Reagent Manufacturing: Used in the formulation of diagnostic kits and assays that rely on controlled protease activity for detection.
• Cell Culture & Biotechnology: Employed to inhibit specific proteases in cell lysates and biological samples to prevent protein degradation during analysis.
• Academic & Industrial R&D: A standard reagent in laboratories for fundamental biochemical studies and high-throughput screening campaigns.

Quality Control

Our Benzamidine is produced and tested under strict quality management systems to ensure batch-to-batch consistency and reliability for your critical applications. We offer various purity grades, including high-purity biochemical and research grades. Comprehensive quality testing includes identity confirmation, purity assay, and impurity profiling. A Certificate of Analysis (COA) detailing all specifications and test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent absorption of atmospheric moisture, which can affect product stability and performance.
