    Yes. Conn's Biological Stains indicates Dichloroindophenol sodium salt in acid is  red and blue in alkali. The product is colorless when reduced.

  7. Other than use as a reagent for determination of Vitamin C, are there other reported uses of Product D1878, 2,6-Dichloroindophenol sodium salt hydrate?

    Yes. Conn's Biological Stains indicates Dichloroindophenol sodium salt has been used as an electron receptor, for use in demonstrating NADPH diaphorase and to stain glutathione reductase electrophoresis gels.

  8. Are there substances known to interfere in Vitamin C determination?

    Yes. Interfering substances are ferrous, stannous, and cuprous sulfite or thiosulfate ions, and SO2.

  9.  Are the absorbance maxima and the extinction coefficients available for Product D1878, 2,6-Dichloroindophenol sodium salt hydrate?

    Our Analytical Department has run absorbance spectra on many lots of D1878. Using 0.1 M phosphate buffer, pH 8.3 as the solvent, absorbance maxima in the range of 600-605 nm and a mM extinction coefficient of 18.0-19.7 have been reported.

  10. Are there published references for Dichloroindophenol sodium salt being used for the determination of Vitamin C?

    Yes. Please see: W. Horowitz ed. Official Methods of Analysis of the AOAC Washington D.C. , 777, (1970) and  K. Hiromi et al., Anal. Biochem. 101, 421, (1980).
