Description
tert-Butanol ROTIPURAN® is a high-purity solvent graded min. 99 %, p.a., ACS, with CAS number 75-65-0 and empirical formula C₄H₁₀O. Key physical data include a molar mass of 74,12 g/mol, density of 0,78 g/cm³, boiling point of 82,41 °C, and flash point below 23 °C, supporting controlled use in analytical and preparative laboratory work. Typical uses include organic synthesis steps, extractions, and analytical sample preparation where a defined tertiary alcohol solvent is specified. Material from manufacturer Carl ROTH is supplied under the ROTIPURAN® designation with the stated minimum assay. UN number 1120 applies for transport classification of this flammable liquid. Laboratories choose this grade when they need consistent solvent quality in a practical for routine analytical chemistry and synthesis support, handled according to standard precautions for low-flash-point alcohols.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about tert-Butanol ROTIPURAN®, min. 99 %, p.a., ACS, 500 ml, glass
What is this article?
tert-Butanol ROTIPURAN®, min. 99 %, p.a., ACS, 500 ml, 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?
