Storage method
Storage Precautions[19] Store in a cool, dry and well-ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 37°C and the container should be kept sealed. It should be stored separately from oxidants, alkalis, active metal powders, etc., and avoid mixed storage. Use explosion-proof lighting and ventilation facilities. It is prohibited to use mechanical equipment and tools that are prone to sparks. The storage area should be equipped with emergency release equipment and suitable containment materials.
Synthesis method
None
Purpose
1. As an introduction agent for trifluoroethyl and trifluoroethoxy agents, the synthetic anesthetics Fluroxene, Isoflurane and Desflurane, and the central nervous system stimulant Flurotidine Flowotyl, proton pump blocker Lansoprazol (PP inhibitor), antiarrhythmic drug Flecamide, analgesic benzodiazepine (Quazepam), dysuria treatment Drug KMD-3213, herbicide Triflusulfuronmethyl.
