Chemical Structure

1-Ethyl-4-N,5-N-dimethyl-1H-imidazole-4,5-dicarboxamide CAS 64-99-3 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 1-Ethyl-4-N,5-N-dimethyl-1H-imidazole-4,5-dicarboxamide.

CATO supplies 1-Ethyl-4-N,5-N-dimethyl-1H-imidazole-4,5-dicarboxamide (CAS 64-99-3), a certified reference material (molecular formula C9H14N4O2, MW 210.23 g/mol) for analytical method development and quality control.

The molecular framework of 1-Ethyl-4-N,5-N-dimethyl-1H-imidazole-4,5-dicarboxamide (C9H14N4O2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
