4667-99-6 Chlorotriethoxysilane Silane, chlorotriethoxy- EINECS 225-112-9 Triethoxychlorosilane (CAS 4667-99-6), molecular formula C6H15ClO3Si and molecular weight 198.72 g/mol, is a CATO reference standard with documented purity and traceability.
4667-99-6 Chlorotriethoxysilane Silane, chlorotriethoxy- EINECS 225-112-9 Triethoxychlorosilane (C6H15ClO3Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), 4667-99-6 Chlorotriethoxysilane Silane, chlorotriethoxy- EINECS 225-112-9 Triethoxychlorosilane 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.
