Chemical Structure
Description
1,2,3,4-Tetrachloro-9-methoxyanthracene (CAS 61601-19-2), molecular formula C15H8Cl4O and molecular weight 346.04 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1,2,3,4-Tetrachloro-9-methoxyanthracene (C15H8Cl4O) is characterized by a hydroxyl group, an ether linkage, 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1,2,3,4-Tetrachloro-9-methoxyanthracene 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.
