Useful:

• Chemical Classes: UVCB
• Canonical SMILES: CC=CC
• Isomeric SMILES: C/C=C/C
• Inhalation Risk: On loss of containment this substance can cause suffocation by lowering the oxygen content of the air in confined areas.
• Effects of Short Term Exposure: Rapid evaporation of the liquid may cause frostbite. Exposure to high concentrations could cause asphyxiation. This may result in unconsciousness, respiratory arrest and death.

Technology Process of

There total 532 articles about which guide to synthetic route it. The literature collected by LookChem mainly comes from the sharing of users and the free literature resources found by Internet computing technology. We keep the original model of the professional version of literature to make it easier and faster for users to retrieve and use.
