Quality Control

Our 4-Nitrophenyl Phosphorodichloridothioate is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Products undergo rigorous analytical testing, 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 R&D and production requirements.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition.
