Description
1,4-Dioxane is an organic solvent offered as ROTIPURAN® grade with a minimum assay of 99,5 %, p.a., ACS, ISO for analytical laboratory use. It carries CAS number 123-91-1 and empirical formula C₄H₈O₂, with a molar mass of 88,11 g/mol and a density of 1,03 g/cm³. The flash point is 11 °C and the boiling range is 100,8 to 101,5 °C, data that support safe handling planning and distillation or reaction setup design. Available from manufacturer Carl ROTH under the ROTIPURAN® designation, it provides a defined cyclic ether medium for dissolution, extraction, and synthesis-related steps in controlled laboratory environments. Typical applications include use as a polar aprotic solvent in organic synthesis support work, sample preparation, and analytical procedures that require a high-purity 1,4-dioxane grade. The combination of stated purity, physical constants, and glass packaging suits research and routine analytical chemistry benches that specify p.a. solvents.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about 1,4-Dioxane, ROTIPURAN®, min. 99.5 %, p.a., ACS, ISO, 1 l, glass
What is this article?
1,4-Dioxane, ROTIPURAN®, min. 99.5 %, p.a., ACS, ISO, 1 l, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Analytical grade solvents (p.a.), inside Solvents, in Lab chemicals.
An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.
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 Analytical grade solvents (p.a.). The catalogue is Lab chemicals.
Shelves beside this one are HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis), Technical & synthesis grade solvents and Green & alternative solvents.
What should I check before I order?
