ADOS (82692-96-4) is a biochemical and chromogenic reagent.

MAOS is a novel Trinder reagent that is a colorimetric probe.

2,6-Dibromoquinone-4-chloroimide is a colorimetric dye for the detection of phenolic compounds. It produces an indigo dye upon reacting with phenolic compounds at a pH of approximately 9.4. 2,6-Dibromoquinone-4-chloroimide has been used as a Gibbs reagent for the colorimetric detection of phenolic compounds. It has also been used in chromogenic reactions for the quantitative colorimetric detection of aflatoxins, causing colorless aflatoxins to become green with an absorption band at 673 nm.

Blue Tetrazolium (Tetrazolium blue), a dye used in microbial research, can be reduced to blue tetrazolium formazan (BTF). It determines succinate dehydrogenase (SDH) activity in yeast strains as a reduced substrate. Extract BTF using DMSO and test its absorption spectrum. BTF exhibits a wavelength range of 480-600 nm with maximal absorbance at 540 nm [1].
