(3,3,4,4,5,5,6,6,6-Nonafluorohex-1-yl)phosphonic acid 503564-50-9 CAS 503564-50-9 chemical structure

Description

The occurrence of (3,3,4,4,5,5,6,6,6-Nonafluorohex-1-yl)phosphonic acid 503564-50-9 is closely related to a phosphonate 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.

CATO supplies (3,3,4,4,5,5,6,6,6-Nonafluorohex-1-yl)phosphonic acid 503564-50-9 (CAS 503564-50-9), a certified reference material (molecular formula C6H6F9O3P, MW 328.07 g/mol) for analytical method development and quality control.

(3,3,4,4,5,5,6,6,6-Nonafluorohex-1-yl)phosphonic acid 503564-50-9 (C6H6F9O3P) contains a phosphonate group, 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.

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), (3,3,4,4,5,5,6,6,6-Nonafluorohex-1-yl)phosphonic acid 503564-50-9 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.
