Cat. No.: HY-15932
CAS No.: 82692-93-1
Synonyms: TOOS sodium salt
TOOS (TOOS sodium salt) is a highly water-soluble aniline derivative widely used in diagnostics and biological experiments. TOOS can be combined with 3-methyl-2-benzothiazolinone hydrazone hydrochloride (MBTH) to form a chromogenic system to measure oxidase activity. In the MBTH-TOOS chromogenic system, MBTH is catalytically oxidized to produce (-NH) free radicals, which react with TOOS to form colorless compounds. Furthermore, the colorless compound undergoes a disproportionation reaction to produce a blue-violet quinoid compound .

CAS No.: 603-48-5
Leucocrystal violet is a cationic triarylmethane dye. Leucocrystal violet generates a colored purple product in the presence of hydrogen peroxide and horseradish peroxidase, or when oxidized by periodate under the catalysis of horseradish peroxidase. Leucocrystal violet serves as a chromogenic reagent for the determination of submicrogram-level hydrogen peroxide, with no interference from tryptophan, persulfate or chromate. Leucocrystal violet reacts with blood to produce a purple/violet color in the presence of hydrogen peroxide; it forms a very weak fluorophore when acting with whole blood in an unbuffered solution, with a maximum absorption wavelength of 630 nm and a maximum fluorescence emission wavelength of 665 nm upon excitation at 630 nm. Leucocrystal violet is widely used for staining blood residues on porous and non-porous materials .
