Catechol violet

CAS: 115-41-3

Catechol violet is a synthetic dye that is used as an optical sensor for the determination of disease activity. This dye has been shown to have synergistic effects with other dyes and a number of analytical methods, such as solid phase microextraction and kinetic energy spectroscopy. Catechol violet binds to covalently-linked proteins and nucleic acids, which can then be detected by a variety of analytical methods such as radiation or thermodynamic data. The kinetic energy of the bond between the dye and covalently-linked proteins can also be used to determine their concentration.
