Description
2-Methyl-1-butanol is an organic alcohol for synthesis offered at a minimum purity of 97,5 %, with CAS number 137-32-6 and empirical formula C₅H₁₂O. The molar mass is 88,15 g/mol and the density is 0,82 g/cm³. Key thermal data include a flash point of 42,5 °C and a boiling range of 127 to 130 °C, supporting safe handling planning and process design in synthetic organic work. The EG number is 205-289-9; the substance is also associated with UN number 1105 for transport classification. This grade is Physical constants from the manufacturer data sheet allow straightforward integration into existing synthesis protocols and risk assessments. Available from manufacturer Carl ROTH, 2-methyl-1-butanol serves as a defined building-block alcohol where controlled purity and documented boiling behaviour are important. It fits general chemical inventories requiring a synthesis-grade C₅ alcohol with transparent specification limits and stable glass packaging for routine bench use.

Questions about 2-Methyl-1-butanol, min. 97.5 %, for synthesis, 100 ml, glass
What is this article?
2-Methyl-1-butanol, min. 97.5 %, for synthesis, 100 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?
