CATECHOL VIOLET AR under Research Lab Fine Chem Industries catalogue.CATECHOL VIOLET AR has been used in the formation of dye-metal complexes. It has also been used to determine Cu2+ chelating activity.
Catechol Violet is used as a complexometric indicator dye. It inhibits the synthesis of globin in reticulocyte lysates. It is also used as a pH indicator with a transition interval from 0 to 8. Soluble in water, ethylene glycol, monomethyl ether and ethanol.
Phenylethyl resorcinol (4-(1-phenylethyl)1,3-benzenediol) (PR) (Figure 1) is a new whitening agent that has been found to have the ability to inhibit tyrosinase activity [1]. PR has been shown to serve as a whitening and brightening ingredient in skin care products, hair lightening products, and cosmetics.
A non-specific photometric metal ion indicator Pyrocatechol Violet (PV) was tested for its potential use in a metal-sensitive optrode membrane. ... It was found that the ability of PV to form complexes with metal ions significantly reduced following immobilisation, with the exception of Cu(II).
