Quality Control

Our production of Dithiophosphoric Acid o-Ethyl S-(1,3-Dihydro-1,3-Dioxo-2H-Isoindol-2-Ylmethyl)o-Isopropyl Ester adheres to a stringent quality management system to ensure batch-to-batch consistency and purity. Each lot undergoes rigorous analytical testing, including HPLC, GC, and NMR, to verify identity, potency, and impurity profiles. Certificates of Analysis (COA) documenting all critical specifications are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from heat, sparks, and open flame.
