4-Trifluoromethoxybenzoic Acid-D4

4-Trifluoromethoxybenzoic Acid-D4 (TFMBA-D4) is a deuterated form of 4-Trifluoromethoxybenzoic Acid (TFMBA) which is a benzoic acid derivative. TFMBA-D4 is a heavy isotope labeled compound with four deuterium atoms replacing the hydrogen atoms in TFMBA. It is primarily used as a stable internal standard in analytical chemistry, specifically in nuclear magnetic resonance (NMR) spectroscopy. TFMBA-D4 is used as an analytical reference standard to quantify TFMBA in various samples. It helps in monitoring the purity and quality of TFMBA in various chemical reactions and processes. TFMBA-D4 has a molecular weight of 217.11 g/mol and a melting point of 127-129°C. It is a white to off-white powder, soluble in common organic solvents such as chloroform, dichloromethane, and ethyl acetate. TFMBA-D4 is usually synthesized by reacting 4-trifluoromethoxybenzoic acid with deuterated hydrogen gas in the presence of a palladium catalyst. The reaction leads to the replacement of hydrogen atoms with deuterium atoms, resulting in the formation of TFMBA-D4. In conclusion, TFMBA-D4 is a useful analytical reference standard in NMR spectroscopy for quantifying TFMBA in various samples. Its chemical properties and synthesis make it a valuable tool in analytical chemistry.
