Recently, several outbreaks of E. coli infections in the U.S. due to eating McDonald's hamburgers have once again raised public concerns about food safety. The 4-Methylumbelliferone derivatives we’re introducing today are key reagents for detecting E. coli, widely used in clinical and microbiological research. The detection process for E. coli utilizes the fluorescence properties of 4-Methylumbelliferone. These unique derivatives can act like tiny labels to track microorganisms. Under UV light, these small molecules emit bright blue fluorescence, helping scientists quickly and accurately identify harmful bacteria.

4-Methylumbelliferone plays a key role in environmental monitoring. It is widely used to detect microorganisms in water and soil to ensure environmental safety. For example, by detecting specific bacterial groups in water, environmental monitoring personnel can quickly determine if the water quality is contaminated and take timely measures to protect public health.

n the field of medical testing, 4-Methylumbelliferone plays an important role. It is used to measure the activity of specific enzymes, aiding doctors in diagnosing diseases. These enzymes play key roles in various physiological and pathological processes, including cell signaling, inflammatory responses, and tumor development. By measuring the activity of these enzymes, doctors can more accurately assess a patient’s health status and develop personalized treatment plans.
