Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 208.21 g/mol gives 1,4-Anthraquinone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,4-Anthraquinone (CAS 635-12-1) is a high-purity analytical reference standard with the molecular formula C14H8O2 and a molecular weight of 208.21 g/mol.
The molecular framework of 1,4-Anthraquinone (C14H8O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, 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), 1,4-Anthraquinone 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.
