Perfluorooctylphosphoric Acid CAS 40143-78-0

Description

Compared with other compounds in its class, the molecular weight of 500.05 g/mol gives Perfluorooctylphosphoric Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Perfluorooctylphosphoric Acid (CAS 40143-78-0), molecular formula C8H2F17O3P and molecular weight 500.05 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Perfluorooctylphosphoric Acid is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 500.05 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.

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.

CATO manufactures Perfluorooctylphosphoric Acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
