Cheméo can also estimate Normal melting (fusion) point, Enthalpy of vaporization at standard conditions, Standard Gibbs free energy of formation, Acentric Factor, Log10 of Water solubility in mol/l for this compound, but they fall outside the models' validated range, so they are not shown here. Open the prediction tool to compute them on demand.

Note: Cheméo is only indexing the data, follow the source links to retrieve the latest data. The source is also providing more information like the publication year, authors and more.
Take the time to validate and double check the source of the data.
Outlier This icon means
that the value is more than 2 standard deviations away from the
property mean.
Compiled This icon marks a compiled value or equation: taken from a data compilation such as ChemSep, not from an original measurement report.
These property values are available through the Cheméo API. A free account gives you an access key.
