Used in plant physiology research to quantify red chlorophyll catabolites (RCC) during senescence and stress responses. Helps scientists study chlorophyll breakdown pathways in leaves, especially during autumn color changes or under environmental stress like drought or pathogen attack. Enables accurate measurement of RCC levels in plant tissues, supporting studies on nutrient recycling, leaf aging, and crop health. Widely applied in agricultural and botanical research to assess plant vitality and optimize harvest or growth conditions.
