Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 478.88 g/mol gives Aureomycin distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Aureomycin (CAS 57-62-5) is a high-purity analytical reference standard with the molecular formula C22H23ClN2O8 and a molecular weight of 478.88 g/mol.
The molecular framework of Aureomycin (C22H23ClN2O8) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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), Aureomycin 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.
