Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Potassium 2,3,5,6-tetrafluorophenolate.
CATO supplies Potassium 2,3,5,6-tetrafluorophenolate (CAS 42289-34-9), a certified reference material (molecular formula C6HF4OK, MW 204.16 g/mol) for analytical method development and quality control.
Potassium 2,3,5,6-tetrafluorophenolate (C6HF4OK) contains a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Potassium 2,3,5,6-tetrafluorophenolate 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.
