Chemical Structure
Description
The occurrence of 3-Amino-4-ethyl-1,2-dihydropyridin-2-one is closely related to an amide group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Amino-4-ethyl-1,2-dihydropyridin-2-one (CAS 34040-82-9), molecular formula C7H10N2O and molecular weight 138.17 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-Amino-4-ethyl-1,2-dihydropyridin-2-one (C7H10N2O) is characterized by an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. 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.
As a certified reference material (CRM), 3-Amino-4-ethyl-1,2-dihydropyridin-2-one 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.
