Used primarily as a reference standard in analytical chemistry, particularly in steroid profiling and doping control. It serves as an internal standard in gas chromatography-mass spectrometry (GC-MS) analyses to detect and quantify endogenous steroids in biological samples. Its structural similarity to cholesterol and other steroidal compounds makes it valuable in metabolic studies, especially in tracing cholesterol oxidation pathways or assessing sample degradation. Also employed in research settings to calibrate instruments and validate methods for steroid hormone analysis.
