Description
trans-Stilbene is an aromatic hydrocarbon offered at min. 97 % purity for organic synthesis and materials research. Registered under CAS number 103-30-0 and EG nr. 203-098-5, it has the empirical formula C₁₄H₁₂, a molar mass of 180,25 g/mol and a density of 1,14 g/cm³. Physical data include a flash point above 110 °C and a boiling range of 306 to 307 °C, supporting thermal handling in standard laboratory setups. The rigid (E)-1,2-diphenylethene scaffold is widely used in photochemistry, fluorescence studies, stilbene-based ligand synthesis and as a model olefin for isomerisation and addition reactions. Its well-defined structure and assay support reproducible spectroscopic work and synthetic transformations. Researchers value trans-stilbene as a reference diarylethene for optical and reactivity studies. The pack size balances convenience with sufficient material for repeated experimental runs and derivative synthesis.

Questions about trans-Stilbene, min. 97 %, 50 g, plastic
What is this article?
trans-Stilbene, min. 97 %, 50 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.
