Description
1,4-Dioxane is a cyclic ether solvent supplied as ROTIDRY® plus with a minimum purity of 99 % and a maximum water content of 50 ppm H₂O, packed with molecular sieve. It is identified by CAS number 123-91-1 and EG number 204-661-8, with the empirical formula C₄H₈O₂, a molar mass of 88,11 g/mol and a density of 1,03 g/cm³. Physical properties include a flash point of 11 °C and a boiling range of 100,8 to 101,5 °C. This 1 l glass bottle format is suited to moisture-sensitive extractions, polymer chemistry and organic reactions that benefit from a stable, moderately polar aprotic medium. The dry ROTIDRY® plus quality from manufacturer Carl ROTH supports reproducible laboratory performance where residual water must remain low. As a flammable liquid, it should be stored and used under controlled conditions with standard laboratory precautions. Ideal for synthetic and analytical workflows requiring a high-assay cyclic ether solvent.

Questions about 1,4-Dioxane, ROTIDRY®, plus min. 99 % (max. 50 ppm H2O), 1 l, glass
What is this article?
1,4-Dioxane, ROTIDRY®, plus min. 99 % (max. 50 ppm H2O), 1 l, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Dry & deuterated solvents (NMR, synthesis), inside Solvents, in Lab chemicals.
A dry solvent has had water removed to a stated level, for a reaction that water would stop. A deuterated solvent replaces hydrogen with deuterium so an NMR spectrum is not drowned by the solvent signal. The isotopic enrichment and the water content are the two specifications. Caps and septa matter, because either product picks up moisture from the air.
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 Solvents. The sub-category is Dry & deuterated solvents (NMR, synthesis). The catalogue is Lab chemicals.
Shelves beside this one are Analytical grade solvents (p.a.), HPLC & LC-MS grade solvents, Technical & synthesis grade solvents and Green & alternative solvents.
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.
