[Studies on "new coccine standard" for the dye standard of the National Institute of Hygienic Sciences].
The "New Coccine Standard (C.I. 16255)" for the Dye Standard of the National Institute of Hygienic Sciences was prepared. The content of this Dye Standard determined by the titanium trichloride method was 97.5% on the average. The ultraviolet-visible absorption and infrared spectra of the Dye Standard were also measured.
