Selivanov reagent is primarily used in analytical chemistry for the detection and identification of carbohydrates, particularly ketoses. It is especially effective in distinguishing ketoses from aldoses based on their reaction products. When applied, the reagent reacts with ketoses to produce a distinct color change, often a red or pink hue, which serves as a visual indicator. This makes it a valuable tool in biochemical and food science research for analyzing sugar composition in various samples. Additionally, it is utilized in educational laboratories to demonstrate carbohydrate differentiation techniques. Its specificity and simplicity make it a practical choice for quick qualitative analysis in both research and teaching settings.
