Description and Uses
Alizarin Red S sodium salt is used as a chromogenic agent for the colorimetric determination of dothiepin hydrochloride in pharmaceutical formulations. It is also used as an ion-pair reagent for the spectrophotometric assay of fexofenadine in pharmaceuticals. It acts as a colorometric pH indicator in the range of 3.8-5.4. Further, it is used in a biochemical assay to determine the presence of calcific deposition by cells of an osteogenic lineage.
