Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 358.64 g/mol gives Icosan-9-ylbenzene distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Icosan-9-ylbenzene (CAS 2398-65-4), molecular formula C26H46 and molecular weight 358.64 g/mol, is a CATO reference standard with documented purity and traceability.
Icosan-9-ylbenzene (C26H46) contains an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
