Lithium triethylborohydride Specification

The Borate(1-),triethylhydro-, lithium (1:1), (T-4)-, with the CAS registry number 22560-16-3 and EINECS registry number 245-076-8, has the systematic name of lithium triethyl(hydrido)borate(1-). It is a kind of colorless to light grey cloudy solution which is sensitive to air and moisture. And the molecular formula of the chemical is C6H16B.Li.

You should be cautious while dealing with this chemical. It is a kind of highly flammable chemical, and will reacts violently with water, and liberates extremely flammable gases. What's more, it may form explosive peroxides, and causes burns. Therefore, you had better take the following instructions: Keep away from sources of ignition - No smoking; Take precautionary measures against static discharges; In case of contact with eyes, rinse immediately with plenty of water and seek medical advice; 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); In case of accident or if you feel unwell, seek medical advice immediately (show label where possible).

Addtionally, the following datas could be converted into the molecular structure:
(1)SMILES: [Li+].CC[BH-](CC)CC
(2)InChI: InChI=1/C6H16B.Li/c1-4-7(5-2)6-3;/h7H,4-6H2,1-3H3;/q-1;+1
(3)InChIKey: WCJAYABJWDIZAJ-UHFFFAOYAV
