Quality Control

Our Sodium O,o-Dicyclohexyl Dithiophosphate is manufactured under strict quality management systems to ensure batch-to-batch consistency and reliability. Each lot undergoes rigorous analytical testing to meet defined specifications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and key parameters is provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and easily oxidized; it is recommended to store under an inert atmosphere (e.g., nitrogen or argon) for long-term stability and to minimize degradation. Keep away from strong oxidizing agents.
