Bromocresol green CAS 76-60-8 BROMOCRESOL BLUE Reagent Grade Chemicals
Description:
The precipitates from acetic acid are fine light yellow crystals. The relative molecular weight was 698.05. The melting point is 218 ~ 219 ℃. It is slightly soluble in water and soluble in ethanol, ether, ethyl acetate and benzene. It is very sensitive to alkali. When it comes to alkaline aqueous solution, it is blue-green. Bromocresol green can be used as an indicator. It is yellow when pH = 3.8 and blue-green when pH = 5.4.
