Quality Control

Our 9-Octadecenoic Acid, 12-Hydroxy-,Tin (2+)Salt (2:1) is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing to ensure consistency and compliance with agreed specifications. A comprehensive Certificate of Analysis (COA) detailing purity, metal content, and physical parameters is provided with every shipment to guarantee traceability and quality assurance for our global B2B clients.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture. Keep away from incompatible materials such as strong oxidizing agents.
