Chemical Structure
Description
As a certified reference material (CRM), 4-((4-((Trimethylsilyl)ethynyl)-phenyl)ethynyl)aniline 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.
4-((4-((Trimethylsilyl)ethynyl)-phenyl)ethynyl)aniline (CAS 176977-39-2), molecular formula C19H19NSi and molecular weight 289.45 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-((4-((Trimethylsilyl)ethynyl)-phenyl)ethynyl)aniline (C19H19NSi) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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.
