Chemical Structure
Description
The molecular framework of (2-Chloro-1-ethoxy-2,2-difluoroethoxy)triethylsilane (C10H21ClF2O2Si) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
(2-Chloro-1-ethoxy-2,2-difluoroethoxy)triethylsilane (CAS 1922958-25-5) is a high-purity analytical reference standard with the molecular formula C10H21ClF2O2Si and a molecular weight of 274.81 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), (2-Chloro-1-ethoxy-2,2-difluoroethoxy)triethylsilane 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.
