Quality Control

Our 4-Fluorophenyl Isothiocyanate is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. A detailed Certificate of Analysis (COA) is provided with every shipment, confirming compliance with agreed specifications. We support cGMP standards for pharmaceutical applications and can tailor purity grades to meet specific project requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its light-sensitive and highly volatile nature, containers should be kept sealed and handled in a fume hood to minimize exposure and prevent degradation.
