Hematein
Hematein (CAS 475-25-2, C16H12O6) is a natural dye, the oxidised form of haematoxylin, derived from the heartwood of logwood trees. Possessing a molecular weight of 300.26 g/mol, it is primarily employed as a biological stain. Its applications are concentrated in histology and cell biology for differential staining of cellular structures, making it an essential reagent for microscopic examination.
Histological Staining
Hematein is a key component in certain staining protocols for histological samples. It is used to differentiate and highlight various tissue components under microscopic examination.
Cell Biology Reagent
In cell biology, Hematein serves as a vital stain for visualizing cellular architecture. It aids in the study of cell morphology and nuclear structures.
Diagnostic Dye
Used in laboratory settings, Hematein acts as a diagnostic dye, assisting in the identification and classification of biological specimens through precise colouration.
