Bromothymol Blue

CAS: 76-59-5
Molecular Formula: C27H28O5SBr2
Molecular Weight: 624.3812
Product description:Crystal powder of shallow rosy, melting point of 200 ~ 202 ℃, soluble in ethanol, ether, methanol and dilute alkali hydroxide solution. Slightly soluble in benzene, toluene and xylene, slightly soluble in water, hardly soluble in petroleum ether. In alkaline solution is blue, yellow in the acid solution.After dissolved carbon dioxide, due to form carbonic acid, carbonic acid is a weak acid, so the pH will not drop too much, turning yellow. Transition of color is green or detection of CO2 generation: to make clear limewater turbid, and bromothymol blue solution change from blue to green to yellow.A ph indicator, indicator adsorption. Often used for aquatic organisms in biology experiment breathing reagent.
