  • Potassium hydrogen phthalate Polarity
    Potassium hydrogen phthalate Polarity Potassium hydrogen phthalate Polarity Potassium hydrogen phthalate (CAS 877-24-7) is an ionic substance for which a molecular dipole moment is not defined. It is ionic: polarity shows up as charge separation and hydration, not as a molecular dipole.
  • Potassium nitride Polarity
    Potassium nitride Polarity Potassium nitride Polarity Potassium nitride (CAS 12030-88-5) is an ionic substance for which a molecular dipole moment is not defined. It is ionic: polarity shows up as charge separation and hydration, not as a molecular dipole.
  • Potassium sulfate Polarity
    Potassium sulfate Polarity Potassium sulfate Polarity Potassium sulfate (CAS 7778-80-5) is an ionic substance for which a molecular dipole moment is not defined. It is ionic: polarity shows up as charge separation and hydration, not as a molecular dipole.
  • Histidine Polarity
    Histidine Polarity Histidine Polarity Histidine (CAS 71-00-1) is polar. C6H9N3O2 has a calculated dipole of about 3.70 D, which follows from its trigonal planar nitrogen centre Snyder polarity index Not conventionally assigned; XlogP3-AA -0.64 (Crippen calculated, RDKit).
  • Hypophosphorous acid Polarity
    Hypophosphorous acid Polarity Hypophosphorous acid Polarity Hypophosphorous acid (CAS 6303-21-5) is polar. It is polar by symmetry, but no dipole magnitude is quoted. Snyder polarity index Not conventionally assigned; XlogP3-AA -0.35 (Crippen calculated, RDKit).
  • Fluorene Polarity
    Fluorene Polarity Fluorene Polarity Fluorene (CAS 86-73-7) is polar. C13H10 has a calculated dipole of about 0.55 D, which follows from its trigonal planar carbon centre Snyder polarity index Not conventionally assigned; XlogP3-AA 3.26 (Crippen calculated, RDKit).
  • Fentanyl Polarity
    Fentanyl Polarity Fentanyl Polarity Fentanyl (CAS 437-38-7) is polar. C22H28N2O has a calculated dipole of about 3.61 D, which follows from its trigonal pyramidal nitrogen centre Snyder polarity index Not conventionally assigned; XlogP3-AA 4.14 (Crippen calculated, RDKit).
  • Sorbic acid Polarity
    Sorbic acid Polarity Sorbic acid Polarity Sorbic acid (CAS 110-44-1) is polar. C6H8O2 has a calculated dipole of about 2.45 D, which follows from its bent oxygen centre Snyder polarity index Not conventionally assigned; XlogP3-AA 1.20 (Crippen calculated, RDKit).
  • Dihydroxyacetone Polarity
    Dihydroxyacetone Polarity Dihydroxyacetone Polarity Dihydroxyacetone (CAS 96-26-4) is polar. C3H6O3 has a calculated dipole of about 1.54 D, which follows from its bent oxygen centre Snyder polarity index Not conventionally assigned; XlogP3-AA -1.46 (Crippen calculated, RDKit).
  • Dichromate ion Polarity
    Dichromate ion Polarity Dichromate ion Polarity Dichromate ion (CAS 13907-47-6) is a molecular ion, for which "polar / nonpolar" is the wrong question. Its polarity follows from structure and symmetry rather than from a calculated dipole. Covers geometry, comparison data, QC strategy and B2B.
