Compared with other compounds in its class, the molecular weight of 266.45 g/mol gives Tri(cyclohexa-2,5-dien-1-yl)silane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Tri(cyclohexa-2,5-dien-1-yl)silane (CAS 1807776-35-7) is a high-purity analytical reference standard with the molecular formula C18H22Si and a molecular weight of 266.45 g/mol.
The molecular framework of Tri(cyclohexa-2,5-dien-1-yl)silane (C18H22Si) 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).
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.
As a certified reference material (CRM), Tri(cyclohexa-2,5-dien-1-yl)silane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
