Chemical Structure
Description
The occurrence of 53612-91-2 potassium fluoride-18f is closely related to fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 53612-91-2 potassium fluoride-18f (CAS 53612-91-2), a certified reference material (molecular formula [18F]K, MW 57.10 g/mol) for analytical method development and quality control.
Owing to fluorine substitution, 53612-91-2 potassium fluoride-18f is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 57.10 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), 53612-91-2 potassium fluoride-18f 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.
