Basic violet 3
CAS:<p>Basic violet 3 is a light-sensitive dye that can be used for the detection of metals. It is a basic dye with a high resistance to water vapor and other solvents. Basic violet 3 has been shown to be carcinogenic in animal studies, but has not been shown to have any adverse effects on humans. The dye reacts with metal hydroxides such as aluminum hydroxide, iron(III) oxide, and calcium hydroxide by absorbing UV radiation. This reaction produces an increased amount of light that can be detected using a spectrophotometer. Basic violet 3 is used in surface methodology because it is able to react with particles and then bind to them through van der Waals forces. Basic violet 3 is also used for kinetic experiments because it provides data about the rate of chemical reactions or chemical processes. Kinetic data from these experiments can be used to determine the mechanism of the reaction or process being studied.</p>Fórmula:C25H30N3·C2H3O2Forma y color:PowderPeso molecular:431.57 g/molBrooker's merocyanine dye
CAS:<p>Brooker's merocyanine dye is a fluorescent dye that has been used in analytical chemistry and fluorescence spectrometry. It is an organic compound that is soluble in water, alcohol, and ether.

CAS:<p>Xylenol orange is a dye used as a pH indicator. It is typically present as the monosodium salt of xylenol and has an optimum concentration of 0.2-0.5 mg/L. Xylenol orange is highly soluble in water and can be used in aqueous solutions, but it should not be used with strong acids or alkalis, as they will cause the dye to precipitate out of solution. Xylenol orange reacts with acidic substances and changes colour from orange to yellow at pH 7.0 or higher. The mechanism behind this reaction involves the deprotonation of xylenol by acid, followed by protonation of the conjugate base, which then undergoes electrophilic substitution by hydroxide ions (OH−).
