Chemical Structure

(2,5-Dimethoxyphenyl)trimethylsilane CAS 72054-75-2 chemical structure

Description

Structurally, (2,5-Dimethoxyphenyl)trimethylsilane (C11H18O2Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 210.34 g/mol, it falls into the medium-molecular-weight range. 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).

(2,5-Dimethoxyphenyl)trimethylsilane (CAS 72054-75-2), molecular formula C11H18O2Si and molecular weight 210.34 g/mol, is a CATO reference standard with documented purity and traceability.

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), (2,5-Dimethoxyphenyl)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.
