Phosphatidylinositol 4-phosphate diC8 (PI(4)P diC8) is a synthetic, purified dioctanoyl PI(4)P.

Phosphoinositides (PIPns) are minor components of cellular membranes but are integral signaling molecules for cellular communication. Phosphatidylinositol 4-phosphate (PI(4)P) is the biosynthetic precursor to PI(4,5)P2 and has an important roles in regulating sphingomyelin and glycosphingolipid metabolism and membrane trafficking at the exit of the Golgi complex.

Alternate names: D-myo-Phosphatidylinositol 4-phosphate, Dioctanoyl Phosphatidylinositol 4-phosphate, PtdIns(4)P C8,  PI(4)P C8, 8:0/8:0 PI(4)P
