Technical Overview & Applications Use-case context
Safranin O, with the chemical formula C20H19ClN4 and CAS number 477-73-6, is a synthetic organic compound used as a biological stain. It is a phenazine-based dye that exhibits a deep red to purple color, depending on the concentration and pH of the solution. Safranin O is commonly employed in histology and cytology for staining cell nuclei, cytoplasm, and other tissue components. The dye is particularly useful for differentiating between various cell types and for highlighting specific cellular structures. Safranin O is also used in the staining of plant tissues, such as roots and stems, to visualize cell walls and other anatomical features. Its high affinity for nucleic acids and other cellular components makes Safranin O a valuable tool in various biological and medical research applications. The dye is typically used in combination with other stains to achieve optimal contrast and visualization.
