Description
Pyrethrin II is a technical-grade mixture supplied at 30 % and described as a mixture of pyrethrin I for laboratory and biochemical applications. The principal component is identified by CAS number 121-29-9 and empirical formula C₂₂H₂₈O₅, with a molar mass of 372,5 g/mol. Physical data include a density of 1,12 g/cm³, a flash point of 203,8 °C, and a boiling point of 473,7 °C. The material is also associated with UN number 3352 for transport classification. This 10 g pack supports analytical reference work, formulation studies, and research on natural pyrethrin esters. Available from manufacturer Carl ROTH, the technical mixture offers a practical source of pyrethrin-related chemistry for controlled experimental use. Clear molecular and physical parameters aid method setup, safety assessment, and reproducible preparation in chemical and biochemical laboratories handling insecticidal natural-product analogues.

Questions about Pyrethrin II, 30 %, technical, mixture of pyrethrin I, 10 g
What is this article?
Pyrethrin II, 30 %, technical, mixture of pyrethrin I, 10 g 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.
Which category should I open next?
