General description
Bromobimane is also known as monobromobimane. It is also a known probe for thiols and is a fluorescent reagent activated upon a photolysis reaction.
Application
Bromobimane is used for the determination of thiols by the HPLC method. It is suitable as a pre-column derivatization agent for fluorometric determination of 2,3-dimercaptopropane-1-sulfonic acid and other dithiols. Bromobimane has been used as a fluorescent label in studying oligomycin-sensitive ATPase from beef heart mitochondria.
Bromobimane has been used for the quantitative measurement of free hydrogen sulfide in vivo and in vitro. It has been used for the labeling of proteins containing thiol groups.
Bromobimane has been used for the quantitative measurement of free hydrogen sulfide in vivo and in vitro. It has been used for the labeling of proteins containing thiol groups.
Biochem/physiol Actions
Bromobimane in solution reacts with small thiol groups (e.g., GSH) and with reactive protein thiol groups (e.g., hemoglobin). The reaction of Bromobimane with thiols is of second-order and dependent on pH and upon reacting with thiolate, it activates the water-soluble fluorescent product for detection.

The bimane fluorescent labels, monobromobimane, dibromobimane, and monobromotrimethylammoniobimane, are derivatives of syn-9,10-dioxabimane:1,5-diazabicyclo[3.3.0]octa-3,6-diene-2,8-dione. They efficiently label hemoglobin (reactive thiol groups), membrane proteins, and glutathione of normal human red cells under physiological conditions. Monobromobimane and dibromobimane are effective on intact cells while
