Quality Control

Our 4-n-Butylphenyl Isothiocyanate is produced and handled under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chromatographic purity assessment and structural confirmation, to ensure it meets the high standards required for research and development applications. A Certificate of Analysis (COA) detailing specific results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen) for long-term storage to prevent moisture absorption and degradation. Recommended storage temperature is 2-8°C for extended stability.
