Chemical Structure
Description
Dimethoxy(methyl)(3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl)silane (CAS 85857-17-6) is a high-purity analytical reference standard with the molecular formula C11H13F13O2Si and a molecular weight of 452.28 g/mol.
The molecular framework of Dimethoxy(methyl)(3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl)silane (C11H13F13O2Si) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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.
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), Dimethoxy(methyl)(3,3,4,4,5,5,6,6,7,7,8,8,8-tridecafluorooctyl)silane 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.
