2-Fluoroanthracene CAS 21454-60-4 chemical structure

Description

2-Fluoroanthracene (CAS 21454-60-4), molecular formula C14H9F and molecular weight 196.22 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to fluorine substitution, a polycyclic aromatic system, 2-Fluoroanthracene is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 196.22 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
