The occurrence of 1,5-Dichloro-9,10-bis(phenylethynyl)anthracene is closely related to chlorine substitution, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 1,5-Dichloro-9,10-bis(phenylethynyl)anthracene (CAS 51580-24-6), a certified reference material (molecular formula C30H16Cl2, MW 447.35 g/mol) for analytical method development and quality control.
The molecular framework of 1,5-Dichloro-9,10-bis(phenylethynyl)anthracene (C30H16Cl2) is characterized by chlorine substitution, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
CATO manufactures 1,5-Dichloro-9,10-bis(phenylethynyl)anthracene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
