P-니트로페닐부틸레이트 화학적 특성, 용도, 생산

• 개요

  P-nitrophenyl butyrate also kown as 4-nitrophenyl butyrate, is a probe for lipase activity. It is hydrolyzed by lipase in the water ambient condition, giving rise to p-nitrophenol and butyric acid. P-nitrophenol actually occurs in the anionic form, p-nitrophenolate, giving a yellowish coloration and absorbing light at 410 nm in an alkaline buffer such as Tris-HCl pH 7.5.

• 정의

  ChEBI: P-nitrophenyl butyrate is a butyrate ester resulting from the formal condensation of the hydroxy group of 4-nitrophenol with the carboxy group of butyric acid. It is a butyrate ester and a C-nitro compound. It is functionally related to a 4-nitrophenol.
