In addition, it is corrosive which may destroy living tissue on contact and may causes burns.

Due to so many dangers mentioned above, you should take different measures to deal with different cases. Wear suitable protective clothing, gloves and eye/face protection. If in case of contact with eyes, rinse immediately with plenty of water and seek medical advice and if in case of accident or if you feel unwell, seek medical advice immediately (show label). After contact with skin, wash immediately with plenty of ... (to be specified by the manufacturer). Besides, take off immediately all contaminated clothing.

As to its usage, it is widely applied in many fields. It could be used in producing semiconductor [semiconducting] material and high purity alloy; It could be used as a dopant for the production of solid-state devices such as transistors, and as a component in low-melting alloys and solders. In addition, it can be used to fight bacterial infections in people with cystic fibrosis.

In addition, you could obtain the molecular structure by using the following datas:
