C22 Sphingomyelin (d18:1/22:0) is widely used in research and pharmaceutical applications due to its role in cell membrane structure and signaling. It is a key component in studying lipid rafts, which are essential for understanding cell communication and membrane organization. This compound is also utilized in the development of drug delivery systems, as it enhances the stability and efficiency of liposomal formulations. Additionally, it plays a significant role in neuroscience research, particularly in investigating myelin sheath formation and neurodegenerative diseases. Its application extends to cosmetics, where it is incorporated into skincare products for its moisturizing and barrier-enhancing properties.
