Quality Control

Every batch of 4-Trifluoromethylthiophenyl Isothiocyanate is manufactured and tested under strict quality management protocols. We ensure compliance with relevant industry standards for fine chemical intermediates. Comprehensive analytical testing, including HPLC for purity and NMR for structural confirmation, is performed. A detailed Certificate of Analysis (COA) documenting identity, purity, and impurity profile is provided with each shipment to guarantee batch-to-batch consistency and reliability for your critical syntheses.

Storage

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