Collection: Chemical Shift Standards for NMR
Chemical Shift Standards for NMR — compiles reference compounds for chemical shifts such as tetramethylsilane (TMS), silyl sulfonate derivatives, and other organosilicon compounds whose signals are sharp and whose positions are stable in NMR spectra. These compounds serve as the zero point or internal or external reference point for reading proton and carbon chemical shifts.
Used by organic and analytical chemistry researchers to calibrate the chemical shift scale (delta) in 1H and 13C NMR spectroscopy, in both organic solvents and water-based solvents such as D2O. Standard selection is tailored to the solvent type, for example sodium silyl sulfonate derivatives for aqueous systems because TMS has poor solubility, while TMS or hexamethyldisiloxane is commonly used in organic solvents.
Example products in this collection: TCI T1638 2039-96-5 Sodium 3-(Trimethylsilyl)-1-propanesulfonate [1H NMR Standard for D2O Solvent], TCI E0064 100-41-4 Ethylbenzene, TCI T0154 75-76-3 Tetramethylsilane [for NMR], TCI H0091 107-46-0 Hexamethyldisiloxane, TCI H0638 1450-14-2 Hexamethyldisilane.
Selection depends on the solubility of the standard in the NMR solvent used, as well as high purity so that the reference signal does not overlap with the sample signals being observed. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on each item's page.
