The occurrence of Trimethyl(3-phenylprop-1-yn-1-yl)silane is closely related to an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Trimethyl(3-phenylprop-1-yn-1-yl)silane (CAS 31683-47-3) is a high-purity analytical reference standard with the molecular formula C12H16Si and a molecular weight of 188.34 g/mol.
Owing to an aromatic ring system, Trimethyl(3-phenylprop-1-yn-1-yl)silane is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 188.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
