1,3-Dihydroxybenzene-d6

1,3-Dihydroxybenzene-d6, also known as resorcinol-d6, is a deuterated analogue of resorcinol, which is a phenolic compound widely used in the chemical industry. The "d6" in the name refers to the six deuterium atoms that have replaced six hydrogen atoms in the molecule, making it an isotopically labeled compound. 1,3-Dihydroxybenzene-d6 is mainly used in research and analytical applications, particularly in the field of NMR spectroscopy. It is used as an internal standard for quantitative analysis of resorcinol, as it provides a reference peak that is easily distinguishable from the peaks of the other compounds in the sample. The use of deuterated internal standards in NMR spectroscopy is essential for accurate quantification of the analyte of interest, as it eliminates the interference caused by the overlapping peaks of the solvent and other impurities. In terms of chemical information, 1,3-Dihydroxybenzene-d6 is a colorless crystalline solid with a molecular formula of C6D6O2 and a molecular weight of 110.14 g/mol. It has a melting point of 111-116 °C and is soluble in water, ethanol, and ether. The deuterium substitution in the molecule does not significantly alter its chemical properties, as the deuterium and hydrogen atoms have similar chemical behaviors. However, the deuterium substitution does affect the NMR spectrum of the compound, as the deuterium atoms have a different magnetic moment and do not split the peaks in the same way as the hydrogen atoms.
