Quality Control

Our Phthiobuzone is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. We provide a Certificate of Analysis (COA) with key specifications including assay, related substances, and residual solvents, confirming compliance with agreed-upon standards. Custom purity grades and specifications are available to meet specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to minimize exposure to atmospheric moisture. Keep away from incompatible materials.
