Separation of Ranolazine

Separation of ranolazine using a C8 aqueous column involves using a column packed with octylsilane-bonded silica, which retains moderately hydrophobic compounds. The C8 column provides a less hydrophobic environment than C18 columns, aiding in the separation of ranolazine from other components. The aqueous mobile phase, combined with organic solvents, interacts differentially with ranolazine, leading to distinct retention times and better resolution of the compound. This setup improves the accuracy and efficiency of analyzing ranolazine in various samples.
