Trisulfide ion Polarity Trisulfide ion Polarity Trisulfide ion (CAS 4362-04-7) 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.
Piperine Polarity Piperine Polarity Piperine (CAS 94-62-2) is polar. C17H19NO3 has a calculated dipole of about 3.46 D, which follows from its bent oxygen centre Snyder polarity index Not conventionally assigned; XlogP3-AA 3.00 (Crippen calculated, RDKit).
Paraffin wax Polarity Paraffin wax Polarity Paraffin wax (CAS 8002-74-2) is a nonpolar material (no molecular dipole defined). It is nonpolar at the level of the repeat unit: The repeat motif is –CH2– with no polar group, so the wax is nonpolar and hydrophobic; the individual
Peroxynitrite ion Polarity Peroxynitrite ion Polarity Peroxynitrite ion (CAS 15637-27-5) 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.
Nitrogen dioxide and nitric oxide Polarity Nitrogen dioxide and nitric oxide Polarity Nitrogen dioxide and nitric oxide (CAS 10102-44-0; 10102-43-9) is polar. It is polar by symmetry, but no dipole magnitude is quoted. Snyder polarity index Not conventionally assigned; XlogP3-AA 0.10 (Crippen calculated, RDKit).
Sodium phosphide Polarity Sodium phosphide Polarity Sodium phosphide (CAS 12058-85-4) 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.
Molybdenum Polarity Molybdenum Polarity Molybdenum (CAS 7439-98-7) is an element, so molecular polarity does not apply. Mo is symmetric, so its bond dipoles cancel and μ = 0 D exactly Covers geometry, comparison data, QC strategy and B2B sourcing notes for industrial buyers.
Magnesium carbonate Polarity Magnesium carbonate Polarity Magnesium carbonate (CAS 546-93-0) 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.
Methyl salicylate Polarity Methyl salicylate Polarity Methyl salicylate (CAS 119-36-8) is polar. C8H8O3 has a calculated dipole of about 2.45 D, which follows from its bent oxygen centre Snyder polarity index Not conventionally assigned; XlogP3-AA 1.18 (Crippen calculated, RDKit).
Malic acid Polarity Malic acid Polarity Malic acid (CAS 6915-15-7) is polar. C4H6O5 has a calculated dipole of about 1.19 D, which follows from its bent oxygen centre Snyder polarity index Not conventionally assigned; XlogP3-AA -1.09 (Crippen calculated, RDKit).
