Description

Arsphenamine is a synthetic organoarsenic compound historically significant in the development of chemotherapeutic agents. Its primary commercial value lies in its role as a key intermediate and reference standard for pharmaceutical research and development. This product is essential for chemical synthesis laboratories, academic research institutions, and companies specializing in the production of fine chemicals and active pharmaceutical ingredients (APIs).

Application

• Pharmaceutical Intermediate: Serves as a critical building block in the synthesis of more complex organoarsenic compounds and specialty chemicals.
• Research & Development: Used as a reference standard and starting material in medicinal chemistry research, particularly in studies of antimicrobial and antiparasitic agents.
• Chemical Synthesis: Employed in organic synthesis for the introduction of arsenic-containing functional groups into target molecules.
• Historical & Educational Reference: Supplied to academic institutions for educational purposes in the history of medicine and chemotherapy.
• Fine Chemical Production: Utilized in the manufacture of high-purity, specialty chemicals for niche industrial and research applications.

Quality Control

Our Arsphenamine is produced under strict quality management protocols to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including identification, assay, and impurity profiling. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee compliance with your specifications and research requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to handle and store the material under an inert atmosphere for long-term stability. Keep away from heat and incompatible materials.
