CAS 517-28-2

Hematoxylin

Description:

Hematoxylin, with the CAS number 517-28-2, is a natural dye derived from the heartwood of the logwood tree (Haematoxylum campechianum). It is primarily used in histology and microscopy as a staining agent, particularly for biological tissues. Hematoxylin exhibits a deep blue to purple color when oxidized, which allows it to effectively bind to nucleic acids, making it valuable for highlighting cell nuclei in tissue samples. The dye is often used in conjunction with eosin, a counterstain, in the widely employed Hematoxylin and Eosin (H&E) staining technique. Hematoxylin is soluble in alcohol and water, and its staining properties can be enhanced through oxidation, typically achieved using agents like sodium iodate or potassium permanganate. In addition to its applications in biological research, hematoxylin has also been explored for potential uses in various fields, including pharmaceuticals and cosmetics, due to its antioxidant properties. However, it is essential to handle hematoxylin with care, as it can be toxic in certain concentrations.

Hematoxylin hydrate

CAS: 517-28-2

Hematoxylin hydrate is a histological stain, which is derived from the heartwood of the logwood tree, Haematoxylum campechianum. This compound undergoes oxidation to become hematein, which then forms a complex with metal ions, commonly aluminum, yielding a dye capable of binding to nucleic acids. The mode of action involves the selective binding to the negatively charged phosphate groups of nucleic acids, primarily in the cell nuclei, resulting in a blue to purple coloration.

Hematoxylin

CAS: 517-28-2

Hematoxylin is a histological stain, derived from the heartwood of the logwood tree (Haematoxylum campechianum), which is a tropical plant native to Central America. Its mode of action involves oxidizing hematoxylin to hematein, which then binds with tissue components in the presence of a mordant, typically aluminum salts. This results in a color change where cell nuclei appear blue or purple under a microscope.
