Chemical Structure

(Dimesitylboryl)(mesityl)diphenylsilane CAS 185672-19-9 chemical structure

Description

Based on its molecular formula C39H43BSi, (Dimesitylboryl)(mesityl)diphenylsilane contains a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 550.66 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

(Dimesitylboryl)(mesityl)diphenylsilane (CAS 185672-19-9) is a high-purity analytical reference standard with the molecular formula C39H43BSi and a molecular weight of 550.66 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.
