Chemical Structure
Description
The molecular framework of 4-(p-Dimethylaminophenyl)-2,6-diphenylpyrylium perchlorate (C25H25N2OClO4) 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).
4-(p-Dimethylaminophenyl)-2,6-diphenylpyrylium perchlorate (CAS 2970-29-8) is a high-purity analytical reference standard with the molecular formula C25H25N2OClO4 and a molecular weight of 468.93 g/mol.
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), 4-(p-Dimethylaminophenyl)-2,6-diphenylpyrylium perchlorate 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.
