Chemical Structure
Description
The occurrence of (2,3-Dimethylphenyl)trimethylsilane is closely related to an organic framework in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2,3-Dimethylphenyl)trimethylsilane (CAS 17961-79-4), molecular formula C11H18Si and molecular weight 178.35 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (2,3-Dimethylphenyl)trimethylsilane (C11H18Si) is characterized by an organic framework. 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.
As a certified reference material (CRM), (2,3-Dimethylphenyl)trimethylsilane 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.
