Chemical Properties	yellow-orange powder
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.
Uses	Alizarin Red S is used in the biochemical assay to determine the presence of calcium.
Definition	ChEBI: An organic sodium salt having 3,4-dihydroxy-9,10-dioxo-9,10-dihydroanthracene-2-sulfonate as the counterion. It is commonly used to stain embryo skeletons in cleared whole mounts, usually of small mammals.
Preparation	Alizarin Red S was prepared by reacting 1,2-Dihydroxyanthracene-9,10-dione with fuming sulfuric acid sulphonate, and translated into Sodium salt.
Biochem/physiol Actions	Alizarin Red S is used for the staining of cartilage and bone. It reacts with calcium, thereby helping in the diagnosis of calcium deposits. It is also used to study carbohydrate–boronic acid interactions.
