product overview
Chloroform-d, containing 0.03 v/v% Tetramethylsilane (TMS), is an essential deuterated solvent specifically engineered for high-resolution Nuclear Magnetic Resonance (NMR) Spectroscopy. This high-purity solvent provides an unprotonated environment, effectively eliminating background signals that would otherwise interfere with the analysis of proton NMR spectra. The inclusion of TMS acts as a crucial internal standard, offering a reliable zero-point reference for accurate chemical shift measurements, which is fundamental for precise structural elucidation of organic compounds. Its excellent dissolving power for a wide range of organic substances, combined with its high isotopic purity, makes it an indispensable tool for chemists, biochemists, and materials scientists. Carefully manufactured to stringent quality standards, this Chloroform-d ensures consistency and reproducibility in spectral data, facilitating breakthroughs in research and enhancing the learning experience in advanced scientific institutions across India. It supports the detailed examination of molecular structures, reaction mechanisms, and quantitative analysis, delivering clarity and confidence in experimental results.
FAQs
1. What is Chloroform-d primarily used for?
It is specifically designed as a deuterated solvent for Nuclear Magnetic Resonance (NMR) spectroscopy, crucial for dissolving samples without interfering with proton signals.
2. Why does this product include 0.03 v/v% TMS?
Tetramethylsilane (TMS) serves as an internal reference standard in NMR spectroscopy, providing a sharp, easily identifiable peak at 0 ppm against which other chemical shifts are measured for accuracy.
3. Is Chloroform-d stable for long-term storage?
Yes, Chloroform-d is generally stable. It should be stored in a tightly sealed container in a cool, dry place, away from light and heat, to maintain its purity and integrity.
4. Can Chloroform-d be used for other analytical techniques?
While primarily optimized for NMR, its high purity and deuteration make it suitable for applications where proton signals need to be minimized, but its specific formulation with TMS is tailored for NMR.
5. How does the deuterated form differ from regular chloroform?
In Chloroform-d, the hydrogen atom of chloroform (CHCl3) is replaced by deuterium (CDCl3). This substitution makes it invisible in proton NMR spectra, allowing the signals from the dissolved sample to be observed clearly without interference from the solvent.
