Description
Styrene is an aromatic monomer supplied at min. 99,5 % purity for synthesis, stabilised, with empirical formula C₈H₈ and CAS number 100-42-5. It has a molar mass of 104,15 g/mol, a density of 0,9 g/cm³, a flash point of 31 °C and a boiling point of 145 °C, making it a well-characterised building block for organic synthesis and polymer-related laboratory work. This grade is 202-851-5. Styrene from manufacturer Carl ROTH is intended for synthetic applications where a high-purity, stabilised alkenylbenzene is required for controlled reactions and intermediate preparation. Chemists use it in laboratory-scale polymerisation studies, functionalisation routes and other synthesis sequences that depend on defined physical properties and assay. The glass bottle format supports secure handling of this flammable liquid under standard laboratory safety practice. With its documented molar mass, density and boiling point, the product integrates readily into documented synthetic protocols and reagent inventories for organic and materials chemistry.
This article belongs on Technical & synthesis grade solvents, in Solvents.

Questions about Styrene, min. 99,5 %, for synthesis, stab., 100 ml, glass
What is this article?
Styrene, min. 99,5 %, for synthesis, stab., 100 ml, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Technical & synthesis grade solvents, inside Solvents, in Lab chemicals.
Technical and synthesis grades are for cleaning, for a coarse extraction and for chemistry that does not end in a chromatogram. They cost less because more impurity is allowed. They are the wrong bottle to make a mobile phase or a volumetric standard.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Solvents. The sub-category is Technical & synthesis grade solvents. The catalogue is Lab chemicals.
Shelves beside this one are Analytical grade solvents (p.a.), HPLC & LC-MS grade solvents, Dry & deuterated solvents (NMR, synthesis) and Green & alternative solvents.
What should I check before I order?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
