Chrome Azurol S is a histological dye used in biomedical research.[1][2]
Chrome Azural S (CAS) is a common
spectrophotometric reagent for detection of certain metals like
aluminum which can be toxic in excess and can contribute to people with
neurodegenerative disorders.[3] CAS is used to provide quantitative and qualitative information on molecules of interest like aluminum and
siderophores.[4] Qualitatively a color change can be observed while also allowing to quantitatively determine concentration of certain
ions.
