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… WebBCN-carbamate-PEG2-Bromide CAS:2243150-62-9 is a chemical compound that consists of a polyethylene glycol (PEG) chain with a BCN (trans-cyclooctene) functional group, a carbamate linker, and a bromide functional group attached to one end.
