CAS号:1263166-91-1 英文名: BCN-PNP (ENDO) ,endo BCN-O-PNB,endo-BCN-PNP-carbonate 中文名:BCN-PNP碳酸盐 CASNumber:1263166-91-1 Molecular formula:C17H17NO5 Molecular weight:315.33 Purity:95% Appearance:white solid 4-Nitrophenol can be used as a pH indicator. A solution of 4-nitrophenol appears colorless below pH 5.4 and yellow above pH 7.5. This color-changing property makes this compound useful as a pH indicator. The yellow color of the 4-nitrophenolate form (or 4-nitrophenoxide) is due to a maximum of absorbance at 405 nm (ε = 18.3 to 18.4 mM cm in strong alkali). In contrast, 4-nitrophenol has a weak absorbance at 405 nm (ε = 0.2 mM cm ). The isosbestic point for 4-nitrop…
