Chemical Structure

9,10-Difluoroanthracene CAS 1545-69-3 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.

9,10-Difluoroanthracene (CAS 1545-69-3), molecular formula C14H8F2 and molecular weight 214.21 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C14H8F2, 9,10-Difluoroanthracene contains fluorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 214.21 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

As a certified reference material (CRM), 9,10-Difluoroanthracene 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.
