Used primarily as a calibration standard in small-angle X-ray scattering (SAXS) experiments due to its well-defined layer spacing of approximately 5.838 nm. Its sharp and consistent diffraction peaks make it ideal for verifying instrument alignment and calibrating the scattering vector (q) scale. Silver behenate is also employed in the characterization of nanostructured materials, such as block copolymers, lipid membranes, and mesoporous materials, where accurate q-scale calibration is critical. Additionally, it serves as a reference in synchrotron and laboratory-based X-ray setups because of its stability and reproducible lamellar structure.
