Description
2,2,5,5-Tetramethyldihydrofuran-3(2H)-one is a cyclic ketone reagent with CAS number 5455-94-7 and the empirical formula C₈H₁₄O₂. It has a molar mass of 142,2 g/mol, a density of 0,926 g/cm³, a boiling point of 149,8 °C, and a flash point of 39,4 °C. The defined furanone scaffold supports exploratory reactions, intermediate preparation, and analytical comparison where this specific structure is required. Material from manufacturer Carl ROTH carries UN number 1224 for transport classification. Physical constants such as density, boiling point, and flash point assist safe handling, solvent selection, and process planning at the bench. Clear CAS, formula, and molar-mass data facilitate accurate weighing, stoichiometry, and traceability in laboratory records.

Questions about 2,2,5,5-Tetramethyldihydrofuran-3(2H)-on, e, 2 g
What is this article?
2,2,5,5-Tetramethyldihydrofuran-3(2H)-on, e, 2 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Fluorescent dyes & labels, inside Dyes, stains & indicators, in Lab chemicals.
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.
