Description

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.

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.
