Description
A red coloring medium made from phenol or carbolic acid. It is soluble in alcohol and ether but insoluble in water. When fabrics were steeped in this solution, the color was nonactinic and therefore safe for darkrooms, windows, and doorways.

Notes
It is soluble in strong acids to form yellow solution, or in aqueous alkalis to form carmine red solutions.
Procedure
Due to this behaviour it can be used as pH indicator with pH transition range 5.0 - 6.8. It is used as an intermediate in manufacturing of dyes.
