Sigma Aldrich Fine Chemicals Biosciences Toluene-d8 99.6 atom D25G
Toluene-d8 is a deuterated NMR solvent useful in NMR-based research and analyses. Spin-lattice relaxation time (T 1) viscosity and density have been measured over -35 to 200C range. The temperature dependent chemical shifts in the proton NMR spectra of -unsaturated ketones in toluene-d8 has been studied.
Sigma Aldrich Fine Chemicals Biosciences Tetrahydrofuran d8 99.5 at
Tetrahydrofuran-d8 (THf-d8 TDf) is a deuterated NMR solvent useful in NMR-based research and analyses. 1H NMR line shape analysis of the exchange rates of proton between methanol and acetic acid dissolved in THf-d8 was reported. It participates as a solvent in the synthesis of deuteriotris[bis(trimethylsilyl)amido]thorium and deuteriotris[bis(trimethylsiiyl)amido]uranium. Dynamic NMR spectroscopic study of 15N 15NAE-dipentadeuterophenylformamidine (DPfA) has been studied in THf-d8.

5α-Cholestane-d6 is the deuterium-labeled (d6) analog of 5α-cholestane supplied as an isotope-labeled reference standard for analytical and synthetic applications. It is intended for use as an internal standard in mass spectrometry, for tracer studies, and for synthetic chemistry where a high-purity, isotopically enriched cholestane derivative is required.
- Deuterium-labeled standard (d6) for isotope dilution and tracing.
- High chemical purity (>98.0%) suitable for analytical use.
- Isotopic enrichment approximately 95 atom % D for clear mass shift.
- Molecular formula C27H42D6; molecular weight 378.71.
- Provided in small quantities appropriate for reference and analytical workflows.
