9-Fluorofluorene CAS 20825-90-5 chemical structure

Description

9-Fluorofluorene (CAS 20825-90-5), molecular formula C13H9F and molecular weight 184.21 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C13H9F, 9-Fluorofluorene contains fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 184.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 9-Fluorofluorene 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.
