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.
Triisopropyl((4-((4-((trimethylsilyl)ethynyl)-phenyl)ethynyl)phenyl)ethynyl)silane (CAS 176977-35-8) is a high-purity analytical reference standard with the molecular formula C30H38Si2 and a molecular weight of 454.79 g/mol.
Owing to a polycyclic aromatic system, Triisopropyl((4-((4-((trimethylsilyl)ethynyl)-phenyl)ethynyl)phenyl)ethynyl)silane is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 454.79 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).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
