p-Nitrophenyl butyrate

Description:

p-Nitrophenyl butyrate is an organic compound that serves as a substrate for various enzymes, particularly esterases. It is characterized by its ester functional group, which is formed from the reaction of p-nitrophenol and butyric acid. This compound typically appears as a yellow crystalline solid, reflecting the presence of the nitro group, which contributes to its distinctive color. p-Nitrophenyl butyrate is soluble in organic solvents such as ethanol and acetone but has limited solubility in water. Its primary use in biochemical research is as a model substrate for studying enzyme kinetics, particularly in the context of enzyme activity assays. The hydrolysis of p-nitrophenyl butyrate by esterases results in the release of p-nitrophenol, which can be quantitatively measured, making it a valuable tool in enzymology. Additionally, due to its nitro group, it may exhibit some degree of toxicity and should be handled with appropriate safety precautions in laboratory settings.

4-Nitrophenyl butyrate

CAS: 2635-84-9

4-Nitrophenyl butyrate is composed of a butyric acid chain esterified with a 4-nitrophenol group, giving it a yellow appearance. This compound is commonly used as a substrate in enzyme assays to measure the activity of esterases and lipases. When these enzymes cleave the ester bond, the nitrophenol group is released, changing the color from yellow to orange. The rate of this color change can be used to determine enzyme activity. Additionally, 4-Nitrophenyl butyrate serves as a reagent in organic synthesis and as an intermediate in dye production.
