.Fluorescein is an organic compound and dye that belongs to the triarylmethine dye family. It has a xanthene tricyclic structural motif and is available as a dark orange/red powder that is slightly soluble in water and alcohol. Fluorescein W/S is a modified form of fluorescein that has been chemically altered to enhance its water solubility. This is typically achieved by adding water-solubilizing functional groups, such as sulfonate (-SO3H) or carboxylate (-COO-) groups, to the fluorescein molecule. These water-soluble modifications make Fluorescein W/S more readily dispersible and stable in aqueous solutions.
