Chemical Structure
Description
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.
Borate(1-), tetrakis(4-fluorophenyl)-, lithium (1:1) (CAS 68140-33-0), molecular formula C24H16BF4Li and molecular weight 398.13 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine substitution, a polycyclic aromatic system, Borate(1-), tetrakis(4-fluorophenyl)-, lithium (1:1) is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 398.13 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), Borate(1-), tetrakis(4-fluorophenyl)-, lithium (1:1) 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.
