Chemical Structure

tert-Butyl 2-oxo-5,6-dihydropyridine-1(2H)-carboxylate CAS 128372-89-4 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including tert-Butyl 2-oxo-5,6-dihydropyridine-1(2H)-carboxylate.

CATO supplies tert-Butyl 2-oxo-5,6-dihydropyridine-1(2H)-carboxylate (CAS 128372-89-4), a certified reference material (molecular formula C10H15NO3, MW 197.23 g/mol) for analytical method development and quality control.

The molecular framework of tert-Butyl 2-oxo-5,6-dihydropyridine-1(2H)-carboxylate (C10H15NO3) 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 its high hydrophobicity (logP), 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
