CAS 17372-87-1
:Eosin
Description:
Eosin, with the CAS number 17372-87-1, is a synthetic dye belonging to the class of xanthene dyes. It is primarily used as a biological stain in histology and cytology, allowing for the visualization of cellular structures under a microscope. Eosin is characterized by its vibrant red to pink color, which results from its conjugated double bond system that allows for effective light absorption. The dye is soluble in water and alcohol, making it versatile for various applications. Eosin is often used in combination with hematoxylin in staining protocols, where it provides contrast to the blue-stained nuclei, highlighting the cytoplasm and other cellular components. Additionally, eosin exhibits fluorescence properties, which can be utilized in fluorescence microscopy. It is important to handle eosin with care, as it can cause irritation upon contact with skin or eyes. Overall, eosin is a valuable tool in biological research and diagnostics, aiding in the study of tissue morphology and cellular characteristics.
