Chemical Structure
Description
9-((Dibenzylmethylsilyl)methyl)-9-dodecyl-9h-9-silafluorene (CAS 18846-40-7) is a high-purity analytical reference standard with the molecular formula C40H52Si2 and a molecular weight of 589.01 g/mol.
Owing to a polycyclic aromatic system, 9-((Dibenzylmethylsilyl)methyl)-9-dodecyl-9h-9-silafluorene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 589.01 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).
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.
