4-Nitrophenyl stearate

4-Nitrophenyl stearate, which is an ester formed by the condensation of stearic acid and 4-nitrophenol, is commonly used as a substrate for enzymatic assays, where the hydrolysis of ester bonds by esterase and lipase can be measured by absorbance or ratio In addition, 4-Nitrophenyl stearate has been used as a model compound to study the enzymatic activity and selectivity of lipases and esterases from various sources. The long hydrophobic tail of the molecule makes it suitable for use in lipophilic Good solubility in the environment makes it a useful probe for studying lipid metabolism.
