Quality Control

Our α-Benzoin Oxime is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, identity, and performance. A Certificate of Analysis (COA) detailing results for assay, melting point, loss on drying, and heavy metals is provided with each shipment to guarantee traceability and compliance with your application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, keep the container tightly sealed when not in use to prevent moisture absorption, which may affect performance. Keep away from incompatible materials.
