OverviewAI-generated
Benzene is a chemical compound with the formula C₆H₆. It has a mass of 78.046950192 and a density of 0.88. The substance melts at 42 and boils at 176. Its vapor pressure is 75, and the speed of sound within it is 1310. Benzene is flammable, with a lower flammable limit of 1.2 and an upper limit of 7.8. Flash points are recorded at 12 and -11.
Safety data indicates an immediately dangerous to life or health level of 1595. Exposure limits include a time-weighted average of 25, a short-term limit of 40, and a ceiling limit of 3. The minimal lethal dose is 170000, while the median lethal dose (LD50) is 10000. Solubility is listed as 0.07, and the ionization energy is 9.25.
In chemical databases, benzene is identified by the IUPAC name benzene and the SMILES string C1=CC=CC=C1. It has a charge of 0, no hydrogen bond donors or acceptors, and a topological polar surface area of 0. The xlogp value is 2.1.
