Tetraethyl difluoromethylenebisphosphonate CAS 78715-58-9

Description

The occurrence of Tetraethyl difluoromethylenebisphosphonate is closely related to a phosphate ester 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.

Tetraethyl difluoromethylenebisphosphonate (CAS 78715-58-9), molecular formula C9H20F2O6P2 and molecular weight 324.20 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H20F2O6P2, Tetraethyl difluoromethylenebisphosphonate contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 324.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Tetraethyl difluoromethylenebisphosphonate 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.
