Properties and stability

Avoid contact with oxides. After decomposition, carbon monoxide, carbon dioxide, sulfur oxide, and hydrogen sulfide can be produced.

Storage method

Stored in a cool, ventilated warehouse. Keep away from fire and heat sources. The storage temperature should not exceed 30. Keep container tightly sealed. They should be stored separately from oxidants, alkalis, and alkali metals, 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 yet

Purpose

Used as daily fragrance.
