Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 254.40 g/mol gives Triethoxy(o-tolyl)silane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Triethoxy(o-tolyl)silane (CAS 18412-55-0) is a high-purity analytical reference standard with the molecular formula C13H22O3Si and a molecular weight of 254.40 g/mol.
The molecular framework of Triethoxy(o-tolyl)silane (C13H22O3Si) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
CATO manufactures Triethoxy(o-tolyl)silane under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
