Description
1-Butanol ROTIPURAN® is an analytical-grade solvent with minimum 99,4 % purity, specified p.a. and ACS, for laboratory use in analysis and sample preparation. Identified by CAS number 71-36-3 and EG nr. 200-751-6, it has the empirical formula C₄H₁₀O, a molar mass of 74,12 g/mol, density 0,81 g/cm³, flash point 35 °C, and boiling point 119 °C. The product is ROTIPURAN® quality targets laboratories that need transparent assay and physical data for method validation and purchasing control. This 1-butanol from manufacturer Carl ROTH sits in the solvents-for-analysis portfolio and supports protocols that call for p.a./ACS alcohol solvents with documented boiling and flash behaviour. Clear CAS, purity, and pack information simplify specification matching and safe handling planning in regulated and research environments.
This article is part of Analytical grade solvents (p.a.), in Solvents.

Questions about 1-Butanol ROTIPURAN®, min. 99.4 %, p.a., ACS, 2.5 l, glass
What is this article?
1-Butanol ROTIPURAN®, min. 99.4 %, p.a., ACS, 2.5 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?
