Chemical Structure

1H,1H,5H-Octafluoropentoxytrimethoxysilane CAS 1429938-98-6 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

1H,1H,5H-Octafluoropentoxytrimethoxysilane (CAS 1429938-98-6), molecular formula C8H12F8O4Si and molecular weight 352.25 g/mol, is a CATO reference standard with documented purity and traceability.

1H,1H,5H-Octafluoropentoxytrimethoxysilane (C8H12F8O4Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine 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), 1H,1H,5H-Octafluoropentoxytrimethoxysilane 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.
