context_page_description: Trimethylsilylpropanoic acid is a chemical compound containing a trimethylsilyl group. It is used as internal reference in the NMR spectrum nuclear magnetic resonance for aqueous solvents. For that use it is often deuterated. Other internal references that are frequently used in NMR experiments are DSS and tetramethylsilane.
context_section_description: Trimethylsilylpropanoic acid (TMSP or TSP) is a chemical compound containing a trimethylsilyl group. It is used as internal reference in the NMR spectrum nuclear magnetic resonance for aqueous solvents (e.g. D₂O). For that use it is often deuterated (3-(trimethylsilyl)-2,2,3,3-tetradeuteropropionic acid or TMSP-d₄). Other internal references that are frequently used in NMR experiments are DSS and tetramethylsilane.
