Questions

  1. What is the wavelength of maximum light absorption of 406317

    1 answer
    1. We do not have a UV-Vis spectrum for either Product 406317 (Isopropyl-9H-thioxanthen-9-one, mixture of 2- and 4-isomers) or the closely related Product 406368 (2,4-Diethyl-9H-thioxanthen-9-one). Given that they are both typically yellow, one might expect absorbance around 420-450 nm.
      This is not necessarily the maximum, but it would be a reasonable wavelength range to try.
