Chemical Structure
Description
((4-((4-Ethynylphenyl)ethynyl)phenyl)-ethynyl)triisopropylsilane (CAS 176977-37-0) is a high-purity analytical reference standard with the molecular formula C27H30Si and a molecular weight of 382.61 g/mol.
The molecular framework of ((4-((4-Ethynylphenyl)ethynyl)phenyl)-ethynyl)triisopropylsilane (C27H30Si) is characterized by a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
