18-(Tert-butoxy)-18-oxooctadecanoic acid（Cat No.:L045508）is a long-chain fatty acid derivative featuring a tert-butoxy group and a ketone functional group at the terminal 18-position of an octadecanoic acid backbone. This modified fatty acid combines hydrophobic and polar characteristics, making it useful in the design of amphiphilic molecules, surfactants, or lipid-based delivery systems. The tert-butoxy moiety can serve as a protecting group or influence solubility and reactivity. It is often employed as an intermediate in organic synthesis, materials chemistry, or pharmaceutical research, particularly where modified lipid-like structures are needed for bioactive formulations.
