Rosolic acid is used as a pH indicator in the range from 5.0 to 6.8. It acts as an intermediate in the manufacturing dyes. It is involved in the activation of heme oxygenase and in the inhibition of DNA fragmentation. It finds application in the selective isolation of coliform bacteria.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
