The journey of Hematoxylin, a natural dye derived from the heartwood of the logwood tree (Haematoxylum campechianum), is as rich and complex as the staining patterns it creates in laboratories worldwide. Identified by its CAS number 517-28-2, Hematoxylin has evolved from ancient dyeing practices to become an indispensable tool in modern scientific and medical research, particularly in the field of microscopy.

Historically, the logwood tree, native to Central America, was a prized commodity. Its wood yielded a potent dye used by indigenous peoples and later by European explorers for textiles, producing vibrant blues and blacks. Its introduction to Europe revolutionized the dyeing industry. However, its true prominence in scientific circles was cemented with its adoption as a key staining agent in histology. The discovery that Hematoxylin, when oxidized to hematein and mordanted with metal salts (most commonly aluminum salts), could effectively stain cell nuclei a deep blue-purple, transformed microscopic tissue analysis.

Today, Hematoxylin is a critical component in two of the most widely used staining techniques: the Hematoxylin and Eosin (H&E) stain and the Papanicolaou (Pap) stain. The H&E stain, a hallmark of histopathology, uses Hematoxylin to color cell nuclei blue and Eosin to stain cytoplasm and extracellular matrix pink, providing pathologists with a clear overview of tissue architecture for diagnosis. In cytology, the Pap stain relies on Hematoxylin for nuclear staining, crucial for identifying cellular abnormalities in samples like cervical smears.

For procurement managers and researchers, understanding the origins and properties of Hematoxylin (CAS 517-28-2) is key to ensuring quality.
