Rhodamine 101 Inner Salt (CAS 116450-56-7)

Rhodamine 101 Inner Salt (CAS: 116450-56-7) is a derivative of the rhodamine family, a group of compounds well-known for their intense fluorescence properties. This particular chemical is characterized by its inner salt structure, also known as a zwitterion, where the molecule contains both positively and negatively charged groups but is overall electrically neutral. This structural feature enhances its solubility in polar solvents while maintaining strong luminescent properties. Rhodamine 101 Inner Salt exhibits a bright red fluorescence when excited by light, typically in the green to yellow range of the spectrum, making it an excellent dye for various applications in scientific research that require high levels of fluorescence stability and intensity. In research settings, Rhodamine 101 Inner Salt is utilized primarily as a fluorescent probe in the study of dynamic processes within cells and tissues, as well as in environmental tracing and analysis. The mechanism of action relies on its ability to absorb light at specific wavelengths and subsequently emit light at a longer wavelength, a property that can be exploited to track and measure biological and chemical processes with high precision. Moreover, due to its strong photostability and the bright nature of its fluorescence, it is frequently used in fluorescence microscopy and spectroscopy techniques. This includes applications such as tracing the distribution of pollutants in water systems or studying the movement and interactions of molecules within live cells, where its distinct fluorescence allows for clear visualization and analysis of complex biological structures and reactions.
