Beschrijving
1-Butyl-1-methyl-pyrrolidinium-bis-(trifluoromethylsulphonyl)-imide (BMPyrr TFSI) is een ionische vloeistof die wordt geleverd met een minimale zuiverheid van 99 % voor laboratoriumoplosmiddel- en groene-chemietoepassingen. De verbinding heeft de empirische formule C₁₁H₂₀N₂F₆S₂O₄, een molaire massa van 422.4 g/mol en een dichtheid van 1.4 g/cm³, met CAS-nummer 223437-11-4. Deze kwaliteit van fabrikant Carl ROTH ondersteunt studies die een gedefinieerd pyrrolidinium TFSI-zout met gedocumenteerde fysische gegevens vereisen. Het materiaal staat vermeld onder groene alternatieve oplosmiddelen en wordt gebruikt waar lage vluchtigheid en ionisch karakter voordelig zijn. Duidelijke identiteitsgegevens—formule, molaire massa, dichtheid en CAS—vergemakkelijken methodeontwikkeling, documentatie en voorraadbeheer.

Questions about BMPyrr TFSI, 25 g, >=99 %, glas
What is this article?
BMPyrr TFSI, 25 g, >=99 %, glas is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Fotometers & spectrofotometers, inside Spectroscopie & fotometrie, in Instrumenten.
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 Spectroscopie & fotometrie. The sub-category is Fotometers & spectrofotometers. The catalogue is Instrumenten.

What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
