Pyrocatechol Violet Chemical Properties,Uses,Production
Chemical Properties
greenish yellow powder
Uses
Pyrocatechol Violet is a complexometric indicator dye. This phthalein dye chelates metals to form blue to blue-violet complexs. It is also a pH indicator with a transition interval from 0 - 8 (red to violet). It is known to be unstable when alkaline. The stability is improved at a neutral pH. When the pH is between 2-7 the color may be yellow. Dyes and metabolites.
Purification Methods
It is recrystallised from glacial acetic acid. It is very hygroscopic and is an indicator standard for metal complex titrations. [Mustafin et al. Zh Anal Khim 22 1808 1967, Beilstein 19/3 V 703.]
