WebAcetonitrile is another very common solvent used in RP-HPLC [184 ]. This solvent has medium polarity ( δ = 11.8 and log Kow = −0.17), a weak hydrogen-bond acceptor, and very weak hydrogen-bond donor capability. Compared to methanol, acetonitrile has slightly higher values for P′ and π ∗ but a higher Kow.
