Description
Tetrahydrofuran SOLVAGREEN® min. 99.5 % est un éther cyclique stabilisé de qualité synthèse, produit à partir de matériau recyclé pour une utilisation plus verte des solvants de laboratoire. Identifié par le numéro CAS 109-99-9 et la formule empirique C₄H₈O, il a une masse molaire de 72.11 g/mol et une densité de 0.883 g/cm³. Le point d'ébullition est de 65 °C et le point d'éclair est de −21.2 °C, reflétant la haute volatilité typique du THF. Fourni dans un conditionnement en verre de 1000 l, ce grade est destiné à la synthèse lorsqu'une pureté minimale de 99.5 % et une stabilisation sont requises. Disponible du fabricant Carl ROTH dans la gamme SOLVAGREEN®, il convient aux laboratoires qui recherchent des solvants à contenu recyclé sans modifier les protocoles THF établis. Les applications courantes comprennent la chimie des polymères, les réactions organométalliques, les extractions et l'emploi comme milieu aprotique polaire polyvalent. Observez les contrôles standard pour solvants inflammables pendant la manipulation, le transfert et le stockage.

Questions about Tetrahydrofuran
What is this article?
Tetrahydrofuran is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Colorants fluorescents & marqueurs, inside Colorants, colorations & indicateurs, in Produits chimiques.
A fluorescent dye absorbs at one wavelength and emits at a longer one. As a label it is attached to a protein, a nucleic acid or a cell. Excitation and emission maxima, and the reactive group if it must conjugate, are the specification. The colour name does not tell you the wavelengths.
A dye or a stain binds, or changes colour, so that something invisible becomes visible. An indicator changes at a pH or a redox point. A fluorescent dye absorbs one wavelength and emits another, which is how a microscope or a plate reader picks it out. The excitation and emission, or the transition interval, are the specification. The colour name on the label is not. Structures are on PubChem under IUPAC names. Methods are in the PubMed literature.
Which category should I open next?
The category is Colorants, colorations & indicateurs. The sub-category is Colorants fluorescents & marqueurs. The catalogue is Produits chimiques.
Shelves beside this one are Colorants & solutions de coloration pour microscopie and Colorants & pigments.
What should I check before I order?
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.
