CAS 76-54-0

2′,7′-Dichlorofluorescein

Description:

2′,7′-Dichlorofluorescein, with the CAS number 76-54-0, is a synthetic organic compound widely used as a fluorescent dye and pH indicator. It exhibits a bright green fluorescence when excited by ultraviolet or blue light, making it valuable in various biological and chemical applications, including microscopy and flow cytometry. The compound has a molecular formula of C13H8Cl2O5 and features two chlorine atoms substituted at the 2' and 7' positions of the fluorescein structure, which enhances its photostability and solubility in aqueous solutions. 2′,7′-Dichlorofluorescein is sensitive to pH changes, displaying distinct fluorescence intensity variations across different pH levels, which allows for its use in monitoring cellular environments. Additionally, it is non-toxic at low concentrations, making it suitable for biological studies. However, like many chemical substances, it should be handled with care, following appropriate safety protocols to avoid exposure.
