Storage method
Storage Precautions[20] Store in a cool, dry and ventilated warehouse dedicated to explosives. The storage temperature does not exceed 32°C and the relative humidity does not exceed 80%. If it contains water as a stabilizer, the storage temperature should not be lower than 1°C, the relative humidity should be less than 80%, and it should be kept away from fire and heat sources. They should be stored separately from oxidants, reducing agents, active metal powders and alkalis, 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. Suitable materials should be available in the storage area to contain spills. Vibration, impact and friction are prohibited.

None yet
Purpose
Used as an explosive and as a pH indicator in analytical chemistry. [21]
