Quality Control

Every batch of 4-Butyl-n-(Diphenylphosphino)Benzenesulfonamide undergoes rigorous analytical testing to ensure it meets the declared specification of minimum 97% purity. Our quality assurance protocol includes identity confirmation via spectroscopic methods and quantitative purity assessment. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance with your research or production standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to handle and store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from strong oxidizing agents.
