Chemical Structure

Pentafluoroethylphosphonic acid dichloride CAS 103304-97-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 236.89 g/mol gives Pentafluoroethylphosphonic acid dichloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Pentafluoroethylphosphonic acid dichloride (CAS 103304-97-8), a certified reference material (molecular formula C2Cl2F5OP, MW 236.89 g/mol) for analytical method development and quality control.

Owing to organophosphorus functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Pentafluoroethylphosphonic acid dichloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 236.89 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.

As a certified reference material (CRM), Pentafluoroethylphosphonic acid dichloride 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.
