Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
(E)-(1-{2,7-dimethylimidazo[1,2-a]pyridin-3-yl}ethylidene)amino 4-methylbenzoate (CAS 478047-81-3) is a high-purity analytical reference standard with the molecular formula C19H19N3O2 and a molecular weight of 321.37 g/mol.
The molecular framework of (E)-(1-{2,7-dimethylimidazo[1,2-a]pyridin-3-yl}ethylidene)amino 4-methylbenzoate (C19H19N3O2) is characterized by a steroid 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
