Chemical Structure
Description
1,2-Dimethoxy-9,10-bis(phenylethynyl)anthracene (CAS 80034-23-7), molecular formula C32H22O2 and molecular weight 438.52 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C32H22O2, 1,2-Dimethoxy-9,10-bis(phenylethynyl)anthracene contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 438.52 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 1,2-Dimethoxy-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.
