Chemical Structure
Description
The molecular framework of Chlorodimethyl(2-phenylpropan-2-yl)silane (C11H17ClSi) is characterized by chlorine substitution. 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Chlorodimethyl(2-phenylpropan-2-yl)silane (CAS 118740-38-8) is a high-purity analytical reference standard with the molecular formula C11H17ClSi and a molecular weight of 212.79 g/mol.
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), Chlorodimethyl(2-phenylpropan-2-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.
