Description
Naphthalene is an aromatic hydrocarbon offered at min. 99 % purity for synthesis, with CAS number 91-20-3 and empirical formula C₁₀H₈. Its molar mass is 128,17 g/mol and density is 1,069 g/cm³. The compound melts and boils under well-defined conditions, with a flash point of 78,5 °C and a boiling point of 218,1 °C, supporting controlled handling in organic preparation work. This grade is suited to laboratory synthesis routes that require a reliable polycyclic aromatic building block, including intermediate formation, recrystallisation studies, and related preparative chemistry. Physical data such as density and boiling behaviour help with solvent selection, reaction setup, and work-up planning. Naphthalene from manufacturer Carl ROTH (EG nr. 202-049-5) provides a consistent synthesis-grade option for research and development laboratories that need a clearly specified aromatic feedstock without unnecessary formulation additives.

Questions about Naphthalene, min. 99 %, for synthesis, 100 g, plastic
What is this article?
Naphthalene, min. 99 %, for synthesis, 100 g, plastic 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.
