Description
n-Heptane ROTICHROM® GC is a straight-chain alkane reference solvent with CAS number 142-82-5 and empirical formula C₇H₁₆, designed for gas-chromatographic standards and analytical laboratory use. It is characterised by a molar mass of 100,20 g/mol, a density of 0,68 to 0,69 g/cm³, a flash point of −4 °C and a boiling point of 98,2 to 98,4 °C, providing well-documented physical properties for calibration and method work. The 5 ml glass pack supplies a convenient small volume for retention-time markers, solvent blanks and qualitative GC applications while limiting surplus material. Offered in the ROTICHROM® GC series from manufacturer Carl ROTH, this n-heptane grade supports chromatography, hydrocarbon analysis and teaching or research settings that require a defined alkane standard. Low density and a narrow boiling interval aid reproducible preparation of dilute mixtures and controlled transfers. The compact glass format integrates easily into laboratory storage and dispensing practices for GC-oriented workflows needing a clearly specified n-heptane reagent.

Questions about n-Heptane, ROTICHROM® GC , 5 ml, glass
What is this article?
n-Heptane, ROTICHROM® GC , 5 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.
