Quality Control

Our Cyclopropyl Isothiocyanate is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including GC, HPLC, and NMR, to ensure high purity and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming identity, purity, and impurity profiles. We adhere to cGMP principles where applicable to support our clients in regulated research and development environments.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at temperatures between 2°C and 8°C (refrigerated) to minimize volatility and degradation. Due to its highly volatile and hygroscopic nature, the container should be allowed to reach ambient temperature before opening to prevent moisture ingress. Keep away from heat, sparks, and open flame.
