Chemical Structure
Description
The occurrence of 4-Oxo-1,4-dihydropyridine-3-carbaldehyde is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-Oxo-1,4-dihydropyridine-3-carbaldehyde (CAS 90490-54-3), a certified reference material (molecular formula C6H5NO2, MW 123.11 g/mol) for analytical method development and quality control.
The molecular framework of 4-Oxo-1,4-dihydropyridine-3-carbaldehyde (C6H5NO2) is characterized by an amino-acid-derived structure, 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.
As a certified reference material (CRM), 4-Oxo-1,4-dihydropyridine-3-carbaldehyde 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.
