Chemical Structure
Description
The occurrence of Heptadecafluorooctanesulfonic Acid Tetraethylammonium Salt is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Heptadecafluorooctanesulfonic Acid Tetraethylammonium Salt (CAS 56773-42-3), molecular formula C8F17O3SC8H20N and molecular weight 629.37 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Heptadecafluorooctanesulfonic Acid Tetraethylammonium Salt is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 629.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), Heptadecafluorooctanesulfonic Acid Tetraethylammonium Salt 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.
