Description
n-Undecane is a straight-chain alkane supplied at min. 95 % purity for synthesis, with empirical formula C₁₁H₂₄ and CAS number 1120-21-4. It has a molar mass of 156,31 g/mol, a density of 0,744 g/cm³, a flash point of 65 °C and a boiling range of 185,8 to 200,5 °C, giving a clearly defined hydrocarbon profile for organic laboratory use. Common applications include use as a non-polar solvent component, reference hydrocarbon, extraction medium, and intermediate in organic preparations where boiling behaviour and density matter for process control. Identification includes EG number 214-300-6 and UN number 2330. Synthesis laboratories select this material when a min. 95 % n-undecane grade with documented physical constants is required for reproducible formulation, calibration, or reaction work involving higher alkanes.

Questions about n-Undecane, min. 95 %, for synthesis, 100 ml, glass
What is this article?
n-Undecane, min. 95 %, for synthesis, 100 ml, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
