Chocolate brown HT

CAS: 4553-89-3

Chocolate Brown HT is a synthetic dye that is used in food, cosmetics, and pharmaceuticals. It is a carcinogen and has been shown to have alerting and activating effects on the central nervous system. It has been shown to be an effective additive for high-performance liquid chromatography due to its labile properties. A study has also demonstrated that this substance can mediate the production of reactive oxygen species, which are known for their role in cancer and other diseases. Chocolate Brown HT also has a statistically significant effect on betaine levels in rats, leading to increased levels of oxidative stress.
