(3,3,3-Trifluoropropyl)triethoxysilane (CAS 681-97-0), molecular formula C9H19F3O3Si and molecular weight 260.33 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, (3,3,3-Trifluoropropyl)triethoxysilane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 260.33 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), (3,3,3-Trifluoropropyl)triethoxysilane 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.
