The physical properties of this chemical are below: (1)#H bond acceptors: 0; (2)#H bond donors: 0; (3)#Freely Rotating Bonds: 0; (4)Polar Surface Area: 0; (5)Exact Mass: 152.921226; (6)MonoIsotopic Mass: 152.921226; (7)Heavy Atom Count: 1; (8)Covalently-Bonded Unit Count: 1.
When you are using this chemical, you should be very cautious. For one thing, it is corrosive which may destroy living tissue on contact. For another thing, it is highly flammable which may catch fire in contact with air, only needing brief contact with an ignition source. And it is spontaneously flammable in air and may causes burns very easily. Then it could react violently with water, liberating extremely flammable gaseshas a very low flash point or evolve highly flammable gases in contact with water.
Therefore, you should take the following advices. 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; If in case of fire use ... (indicate in the space the precise type of fire-fighting equipment. If water increases the risk add - Never use water); And if in case of accident or if you feel unwell, seek medical advice immediately (show the label where possible). Then do not breathe gas/fumes/vapour/spray (appropriate wording to be specified by the manufacturer) and take off immediately all contaminated clothing after contacting. When you are storing it, keep container tightly closed and dry.
Additionally, you could convert the following datas into the molecular structure:
(1)Canonical SMILES: [Eu]
(2)InChI: InChI=1S/Eu
(3)InChIKey: OGPBJKLSAFTDLK-UHFFFAOYSA-N
