Description
Tetramethylsilane is a high-purity organosilicon reference compound supplied at min. 99,9 % for NMR spectroscopy. Identified by CAS number 75-76-3 and empirical formula C₄H₁₂Si, it has a molar mass of 88,22 g/mol and a density of 0,63 g/cm³. The boiling point lies between 26 and 27 °C, with a flash point below −30 °C, underscoring the need for careful handling in analytical workflows. This grade is widely used as an internal chemical-shift standard in proton and carbon NMR because of its sharp, well-defined resonance and chemical inertness under typical measurement conditions. Physical data including density and molar mass support straightforward preparation of calibration solutions and sealed reference capillaries. EG nr. 200-899-1 further identifies the substance for regulatory documentation in laboratory chemical inventories.

Questions about Tetramethylsilane, min. 99.9 %, for NMR-spectroscopy, 25 ml, glass
What is this article?
Tetramethylsilane, min. 99.9 %, for NMR-spectroscopy, 25 ml, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Photometers & spectrophotometers, inside Spectroscopy & photometry, in Lab instruments.
A photometer reads absorbance at one or a few wavelengths. A spectrophotometer scans or selects many. Both send light through a cuvette or a well. The wavelength range, UV or visible, and the bandwidth decide what can be measured. A visible-only instrument cannot read a nucleic acid at 260 nm.
A photometer or spectrophotometer sends light through a sample and reads how much was absorbed. In the range where the Beer–Lambert relation holds, absorbance tracks concentration. A refractometer reads how a liquid bends light, which tracks dissolved solids. A polarimeter reads the rotation of polarised light, the classical measurement for sugars. The lamp, the wavelength and the cuvette path length are the three things that have to be right before the number means anything. The optical quantities trace to NIST and the BIPM.
