Used in biochemical research as a marker for sterol oxidation and metabolism in plants. Serves as a biomarker for detecting lipid peroxidation in plant tissues, which is associated with stress responses, aging processes in plants, and degradation of plant-based products. Studied in plant physiology and food science for evaluating the stability of phytosterols in oils and extracts. Acts as a reference standard in analytical chemistry, particularly in gas chromatography and mass spectrometry, for identifying steroidal compounds in complex plant mixtures and natural products.
