Description
ES9-17 is a biochemical research compound offered at a minimum purity of 95 % for professional laboratory use. Identified by CAS number 55854-43-8 and the empirical formula C₁₀H₈BrNO₂S₂, it has a molar mass of 318,21 g/mol, giving a clear chemical identity for documentation, ordering and experimental records. The material is ES9-17 supports work with specialised bromine- and sulphur-containing organic structures in biochemical and chemical research settings. Identity data including CAS, formula and molar mass help laboratories maintain consistent inventory control and traceability across projects. Available from manufacturer Carl ROTH, this grade is positioned for controlled research environments rather than bulk process chemistry. The defined minimum assay of 95 % aids batch-to-batch comparison in exploratory and confirmatory experiments. Compact packaging reduces unnecessary stock while keeping the reagent readily available for screening, reference preparation or focused synthetic and analytical tasks in academic and industrial life-science laboratories.

Questions about ES9-17, min. 95 %, 25 mg
What is this article?
ES9-17, min. 95 %, 25 mg 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.
