14348-40-4 - Reference Information
| Biological activity | TBHBA (2,4,6-Tribromo-3-hydroxybenzoic acid) is a highly stable dye formed by oxidative coupling reaction with 4-aminoantipyrine (4-AA) or 3-methylbenzothiazolone hydrazone (MBTH) in the presence of hydrogen peroxide and peroxidase. |
| Use | Used as biochemical reagent Ultrapure biochemical reaction chromogen. With good water solubility, high sensitivity and strong stability enzyme colorimetric determination, "TBHBA" uric acid is oxidized by uricase in allantoin, and the produced hydrogen peroxide reacts with 4-aminoantipyrine and 2,4, 6-tribromo-3-hydroxybenzoic acid to form Chinonimine. |
