Description
alpha-Ionone is a pure cyclic ketone with CAS number 127-41-3 and the empirical formula C₁₃H₂₀O. It has a molar mass of 192,30 g/mol and a density of 0,922 g/cm³, together with a flash point of 87,3 °C and a boiling point of 207,7 °C. These well-defined physical data support reliable handling in organic synthesis, analytical reference work, and fragrance-related laboratory studies. The substance is supplied as a pure grade in a 25 ml glass pack from manufacturer Carl ROTH, suited to bench-scale use where a characterised alpha-ionone material is required. Researchers apply it in isomer comparison, method development, and work on terpenoid and aroma compounds that depend on structural specificity. Clear molar mass, density, and thermal values aid experimental design, documentation, and risk assessment. Identification is completed by EG number 204-841-6, which assists inventory and regulatory tracking in chemical laboratories. The compact glass unit is practical for controlled dispensing and routine research workflows.

Questions about alpha-Ionone, pure, 25 ml, glass
What is this article?
alpha-Ionone, pure, 25 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.
