Quality Control

Our (1S)-(+)-Camphorquinone is manufactured under strict quality management systems. Each batch is tested to ensure it meets high-purity standards suitable for dental and photopolymer applications. A comprehensive Certificate of Analysis (COA) detailing purity, chiral purity, and impurity profiles is provided with every shipment to guarantee traceability and batch-to-batch consistency.

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). Keep away from heat and incompatible materials. Due to its light-sensitive nature, containers should be kept sealed and opaque or stored in amber glass/darkened conditions.
