Chemical Structure
Description
CATO supplies Ethyl 1-(4-formyl-2-nitrophenyl)-4-piperidinecarboxylate (CAS 885949-64-4), a certified reference material (molecular formula C15H18N2O5, MW 306.31 g/mol) for analytical method development and quality control.
The molecular framework of Ethyl 1-(4-formyl-2-nitrophenyl)-4-piperidinecarboxylate (C15H18N2O5) 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 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.
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.
