Molar mass and elemental composition are computed from IUPAC 2021 conventional atomic weights. Formula, exact mass and the computed descriptors come from PubChem, which is US government work and in the public domain. Melting point, boiling point and density come from Wikidata under CC0. Properties with no figure shown are absent from those sources rather than zero.
