Green and lean: A validated RP-HPLC-VWD method for simultaneous determination of hydroquinone, methylparaben, fluocinolone acetonide, and propylparaben.
This study investigated the optimization, development, and validation of an accurate, precise, and sensitive reversed-phase high-performance liquid chromatographic technique with variable-wavelength detection (RP-HPLC-VWD) method for the rapid determination of four active ingredients (APIs) of hydroquinone (HYQ), methy...
