Quality Control

Our o-Phenyl Ditetrahydro-1(2H)-Pyridazinylphosphinothioate is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity and NMR/IR for structural confirmation, to ensure it meets precise customer specifications and high-purity research standards. A comprehensive Certificate of Analysis (COA) documenting identity, purity, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at a controlled room temperature (15-25°C). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation. Keep away from heat, sparks, and open flame.
