Dimethylbis(2-methyl-3H-cyclopenta[a]naphthalen-3-yl)silane (CAS 150096-53-0), molecular formula C30H28Si and molecular weight 416.63 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a polycyclic aromatic system, Dimethylbis(2-methyl-3H-cyclopenta[a]naphthalen-3-yl)silane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 416.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
