Campestanol is a natural phytosterol. Chemical formula C28H50O. Molar mass 402.707 g mol-1. Values are given for materials in their standard state (at 25 °C [77 °F], 100 kPa). Campestanol is typically obtained as a white to off-white crystalline solid with very low solubility in water and good solubility in common organic solvents such as ethanol, chloroform and hexane. It is optically active and handled as a non-volatile, non-hygroscopic substance under normal laboratory conditions. Typical handling and storage recommendations are refrigeration or controlled room temperature in tightly closed containers, protected from light and moisture. Identification is commonly performed by GC or GC-MS after derivatization, by HPLC with appropriate detectors, and by spectroscopic methods such as 1H and 13C NMR and IR for structural confirmation.
