Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 406.48 g/mol gives Azatadine Dimaleate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Azatadine Dimaleate (CAS 3978-86-7), a certified reference material (molecular formula C20H22N2C4H4O4, MW 406.48 g/mol) for analytical method development and quality control.
The molecular framework of Azatadine Dimaleate (C20H22N2C4H4O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
