Quality Control

Our Butyl Isothiocyanate is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including assay by GC or HPLC, identity confirmation (IR), and impurity profiling to ensure it meets precise specifications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment, ensuring full traceability and compliance with customer and industry requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place away from heat sources and incompatible materials. Due to its highly volatile and easily oxidized nature, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term stability. Keep container tightly sealed when not in use to prevent evaporation and moisture ingress.
