Description
Delta-Valerolactone is a six-membered lactone offered at a minimum purity of 95 % for laboratory and biochemical research. Identified by CAS number 542-28-9 and the empirical formula C₅H₈O₂, it has a molar mass of 100,12 g/mol and a density of 1,113 g/cm³. The flash point is 112 °C. Delta-Valerolactone (Carl ROTH) gives users documented physicochemical parameters that support accurate weighing, transfer, and process planning. Density data aid volumetric handling, while the flash-point value informs safe thermal and storage practices in the laboratory. The stated purity grade enables consistent performance when the lactone is used as a building block, intermediate, or reference compound. This biochemical reagent is intended for professional scientific environments where reliable CAS identity, formula, and specification data are essential. Transparent molar-mass and density figures further simplify stoichiometric calculations, inventory management, and experimental documentation across research workflows.

Questions about Delta-Valerolactone, min. 95 %, 250 g
What is this article?
Delta-Valerolactone, min. 95 %, 250 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.
