Chemical Structure
Description
CATO supplies 1,4,6,7-Tetrachloro-9,10-bis(phenylethynyl)anthracene (CAS 80034-20-4), a certified reference material (molecular formula C30H14Cl4, MW 516.24 g/mol) for analytical method development and quality control.
The molecular framework of 1,4,6,7-Tetrachloro-9,10-bis(phenylethynyl)anthracene (C30H14Cl4) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 1,4,6,7-Tetrachloro-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.
