Used in research on cell signaling pathways, particularly in studies involving phosphoinositide metabolism. Serves as a synthetic analog of natural phosphatidylinositol to investigate membrane dynamics and lipid-protein interactions. Employed in the formulation of liposomes for drug delivery systems due to its ability to mimic components of biological membranes. Also utilized in biochemical assays to study enzyme activity, such as phospholipase action, and in the development of model membranes for biophysical studies.
