Biochemical colorimetric reagents

Biochemical colorimetric agents are a type of reagent used for biochemical reaction detection. They react with specific molecules or ions to produce visible color changes, thus achieving qualitative or quantitative analysis. These colorimetric agents are widely used in clinical diagnosis, environmental monitoring, and scientific research experiments, with the advantages of simple operation, high sensitivity, and low cost.
