Quality Control

Our p-(2-Phenylhydrazino)Phenyl p-Toluenesulphonate is manufactured under controlled conditions and undergoes rigorous analytical testing to ensure batch-to-batch consistency and high purity. Quality is verified through multiple techniques including HPLC, NMR, and IR spectroscopy. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance protocols.

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 light-sensitive and easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Keep away from heat, sparks, open flames, and incompatible materials.
