4-NITROPHENYL TRIFLUOROACETATE Usage And Synthesis
| Chemical Properties | Beige crystalline |
| Uses | 4-Nitrophenyl Trifluoroacetate is used as a reagent for the preparation of 4-nitrophenyl active esters from acids. |
| Purification Methods | Recrystallise the ester from CHCl3/hexane [Margolis et al. J Biol Chem 253 7891 1978]. It sublimes in vacuo (m 36-38o). It is moisture sensitive. [Sakakibara & Inukai Bull Chem Soc Jpn 37 1231 1964.] |
| Precautions | 4-Nitrophenyl Trifluoroacetate is water sensitive; should be stored in a tightly closed bottle. |
