8-((2-Chloro-3-((10,11-dihydro-9H-benzo[a]xanthen-8-yl)methylene)cyclohex-1-enyl)methylene)-8,9,10,11-tetrahydrobenzo[a]xanthenium perchlorate (CAS 62580-63-6) is a high-purity analytical reference standard with the molecular formula C42H34ClO2ClO4 and a molecular weight of 705.63 g/mol.
8-((2-Chloro-3-((10,11-dihydro-9H-benzo[a]xanthen-8-yl)methylene)cyclohex-1-enyl)methylene)-8,9,10,11-tetrahydrobenzo[a]xanthenium perchlorate (C42H34ClO2ClO4) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, a polycyclic aromatic system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
