Chemical Structure
Description
1,1,4,4,7,7,10,10-Octamethyl-2,3,4,7,8,9,10,12-octahydro-1H-dibenzo[b,h]fluorene (C29H38) contains a polycyclic aromatic 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).
1,1,4,4,7,7,10,10-Octamethyl-2,3,4,7,8,9,10,12-octahydro-1H-dibenzo[b,h]fluorene (CAS 77308-48-6) is a high-purity analytical reference standard with the molecular formula C29H38 and a molecular weight of 386.61 g/mol.
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.
