Chemical Structure
Description
The occurrence of 1,5,9,10-Tetrachloroanthracene is closely related to chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
1,5,9,10-Tetrachloroanthracene (CAS 82843-47-8) is a high-purity analytical reference standard with the molecular formula C14H6Cl4 and a molecular weight of 316.01 g/mol.
Based on its molecular formula C14H6Cl4, 1,5,9,10-Tetrachloroanthracene contains chlorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 316.01 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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), 1,5,9,10-Tetrachloroanthracene 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.
