Description
p-Cymene is an aromatic hydrocarbon of empirical formula C₁₀H₁₄ and CAS number 99-87-6, supplied at a minimum purity of 98,5 %. It has a molar mass of 134,22 g/mol, a density of 0,857 g/cm³ and a boiling range of 176 to 178 °C, giving a clear physical profile for laboratory handling. This grade is packed as 500 ml in glass and is intended for organic synthesis, fragrance and flavour research, and analytical workflows that require a defined alkyl-substituted benzene. The compound is identified under EG number 202-796-7 and UN number 2046, supporting inventory control and transport classification. Available from manufacturer Carl ROTH, p-cymene serves as a versatile intermediate and reference material in method development, extraction studies and formulation trials. Its monoterpene-related structure makes it useful where reproducible boiling behaviour and documented identity matter. The glass bottle presentation suits routine bench use while protecting the liquid during storage and transfer. Chemists can integrate this reagent into multi-step syntheses, calibration work and quality-control procedures that depend on consistent purity and well-characterised physicochemical data.

Questions about p-Cymene, min. 98,5 %, 500 ml, glass
What is this article?
p-Cymene, min. 98,5 %, 500 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.
