Homepage, Shamash, Research Resources, Quest for Dicyanin, Dicyanine A, Pinacyanol

Pinacyanol refers to a family of functional dyes used to sensitize photographic film to the red, far red, and near infra-red spectrums. One variety was marketed as Sensitol Red by Ilford for this purpose in the 1920s. Modern use lies in scientific imaging, such as astrophotography, or in the manufacture of CDs and DVDs.

Our interest in the substance lies in the fact that a Mr. Oscar Bagnall determined that it had an activity like Dicyanine A in that it enhanced the ability to see the human aura. In addition, it was more stable than Dicyanine A, and (at the time, at least,) less expensive.
