A Zero absorption spectrum of 8 µg/ml HCQ overlaid with 8 µg/mL PARA and a mixture of 4µg/mL HCQ & 4 µg/mL PARA revealed that 266 nm is an Iso absorptive point and revealed that 266 and 313.5 nm has the same absorbance in HCQ. B Zero absorption spectra of HCQ measured at 220 nm. C Zero absorption of PARA measured at 242.5 nm
