1,2,3,4-Tetramethylbenzene-d14

1,2,3,4-Tetramethylbenzene-d14, also known as p-Terphenyl-d14, is a deuterated (heavy hydrogen) form of the aromatic hydrocarbon tetramethylbenzene. This compound is used as a labeled internal standard in a variety of analytical applications such as gas chromatography-mass spectrometry (GC-MS) and nuclear magnetic resonance (NMR) spectroscopy. The deuterium labeling of 1,2,3,4-Tetramethylbenzene-d14 provides several advantages over the unlabeled compound in analytical applications. Firstly, it allows for increased sensitivity and specificity in the detection of the compound due to the unique isotopic signature of deuterium. Secondly, it allows for accurate quantification of samples as the internal standard is chemically identical to the analyte of interest apart from the isotopic labeling. The chemical formula of 1,2,3,4-Tetramethylbenzene-d14 is C10D14H10 and its molecular weight is 154.29 g/mol. Its melting point is -13°C and its boiling point is 230°C. The compound is soluble in organic solvents such as ethanol, methanol, and acetone, but is insoluble in water. In terms of safety, 1,2,3,4-Tetramethylbenzene-d14 is considered to be of low toxicity. However, as with all chemicals, proper handling procedures and personal protective equipment should be used when working with this compound.
