Description
1-Butyl-1-methyl-pyrrolidinium-bis-(trifluoromethylsulphonyl)-imide (BMPyrr TFSI) is an ionic liquid supplied at a minimum purity of 99 % for laboratory solvent and green-chemistry applications. The compound has the empirical formula C₁₁H₂₀N₂F₆S₂O₄, a molar mass of 422,40 g/mol and a density of 1,4 g/cm³, with CAS number 223437-11-4. This grade from manufacturer Carl ROTH supports studies that require a defined pyrrolidinium TFSI salt with documented physical data. The material is listed among green-alternative solvents and is used where low volatility and ionic character are advantageous. Clear identity data—formula, molar mass, density and CAS—facilitate method development, documentation and inventory control.

Questions about BMPyrr TFSI, 25 g, >=99 %, glass
What is this article?
BMPyrr TFSI, 25 g, >=99 %, 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.
Which category should I open next?
The category is Spectroscopy & photometry. The sub-category is Photometers & spectrophotometers. The catalogue is Lab instruments.
