Quality Control

Our o-Tolidine Dihydrofluoride is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing specific results for purity, assay, and impurity profiles is provided with each shipment to guarantee it meets your technical requirements.

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 to prevent degradation. Keep away from strong alkalis and incompatible materials.
