Chemical Structure
Description
The molecular framework of 142761-78-2 (3-Ethynyl-4-{[tri(propan-2-yl)silyl]ethynyl}hex-3-ene-1,5-diyne-1,6-diyl)bis[tri(propan-2-yl)silane] DTXSID90565714 (C37H64Si3) is characterized by an aromatic ring 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
142761-78-2 (3-Ethynyl-4-{[tri(propan-2-yl)silyl]ethynyl}hex-3-ene-1,5-diyne-1,6-diyl)bis[tri(propan-2-yl)silane] DTXSID90565714 (CAS 142761-78-2) is a high-purity analytical reference standard with the molecular formula C37H64Si3 and a molecular weight of 593.16 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.
