Description
2-Methyltetrahydrofuran SOLVAGREEN® est un solvant extra pur avec une teneur minimale de 99 %, stabilisé avec BHT pour un usage fiable en laboratoire. Identifié par le numéro CAS 96-47-9 et la formule empirique C₅H₁₀O, il a une masse molaire de 86.13 g/mol, une densité de 0.86 g/cm³, un point d'ébullition de 78 °C et un point d'éclair de −10 °C. Le solvant est fréquemment choisi pour la synthèse organique, les extractions et la chimie des procédés lorsqu'un milieu d'éther cyclique est préféré. Cette variante est disponible du fabricant Carl ROTH dans la ligne SOLVAGREEN®, elle offre un profil de pureté défini adapté aux flux de travail de synthèse. Ses propriétés physiques facilitent la manipulation dans des conditions inertes ou ventilées standard, typiques des éthers à bas point d'ébullition. Les chimistes utilisent 2-methyltetrahydrofuran comme solvant éthéré de remplacement en chimie organométallique, dans les séquences de couplage croisé et dans d'autres voies préparatives qui bénéficient de ses caractéristiques de solvatation et de sa plage d'ébullition.
Cet article fait partie de Solvants verts & alternatifs, dans Solvants.

Questions about 2-Methyltetrahydrofuran, SOLVAGREEN® min. 99 %, extra pur, 250 ml, verre
What is this article?
2-Methyltetrahydrofuran, SOLVAGREEN® min. 99 %, extra pur, 250 ml, verre is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Solvants verts & alternatifs, inside Solvants, in Produits chimiques.
A green or alternative solvent is chosen to replace a more hazardous one, often with a higher boiling point or a different polarity. It is not automatically equivalent in a method. The replacement has to dissolve the same compounds and leave the same impurities behind, which is a test, not a label.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvants. The sub-category is Solvants verts & alternatifs. The catalogue is Produits chimiques.

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.
