Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 430.54 g/mol gives 2,7-Dihexylpyrene-4,5,9,10-tetraone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,7-Dihexylpyrene-4,5,9,10-tetraone (CAS 837421-18-8), molecular formula C28H30O4 and molecular weight 430.54 g/mol, is a CATO reference standard with documented purity and traceability.
2,7-Dihexylpyrene-4,5,9,10-tetraone (C28H30O4) contains a steroid core, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
