Description
tert-Butyldimethylsilyl trifluoromethanesulfonate is a silylating reagent with CAS number 69739-34-0 and empirical formula C₇H₁₅F₃O₃SSi. It has a molar mass of 264,34 g/mol and a density of approximately 1 g/cm³, supporting controlled introduction of the tert-butyldimethylsilyl protecting group in organic and biochemical synthesis. The material is offered from manufacturer Carl ROTH for research and development use in chemical and biochemical settings. Its defined molecular composition and physical data help ensure reproducible handling when preparing silyl ethers or related intermediates. Typical applications include multi-step organic synthesis, protecting-group chemistry, and method development where a compact, well-characterised TBDMS triflate source is preferred. UN number 2920 applies for transport classification according to the manufacturer data.

Questions about tert-Butyldimethylsilyl trifluoromethane, sulfonate, 50 g
What is this article?
tert-Butyldimethylsilyl trifluoromethane, sulfonate, 50 g 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.
