4-Nitrophenyl palmitate

4-Nitrophenyl hexadecanoate; Palmitic acid 4-nitrophenyl ester

4-Nitrophenyl palmitate is a lipase-sensitive chromogenic substrate commonly used in the study of lipase and esterase activity. Its hydrolysis by lipases produces a yellow 4-nitrophenol, which can be easily detected spectrophotometrically, offering a quantitative measure of enzyme activity. This substrate is widely utilized in the screening of lipase-producing microorganisms and the optimization of enzyme-catalyzed reactions in various fields, including biotechnology and pharmaceutical research.

4-Nitrophenyl palmitate is a colorimetric lipase and esterase substrate. Upon enzymatic hydrolysis of 4-nitrophenyl palmitate, 4-nitrophenol is released which can be quantified by colorimetric detection at 410 nm as a measure of enzyme activity. 4-Nitrophenyl palmitate has been used to characterize the activity of various bacterial and mammalian enzymes, including Burkholderia and porcine pancreatic lipases.

P-nitrophenyl palmitate is a palmitate ester obtained by condensation of the carboxy group of palmitic acid with the phenolic hydroxy group of p-nitrophenol. It is a hexadecanoate ester and a C-nitro compound. It derives from a 4-nitrophenol.
