2,5,8-Trimethylimidazo[1,2-a]pyrazine-3,6(5H,7H)-dione CAS 194666-10-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,5,8-Trimethylimidazo[1,2-a]pyrazine-3,6(5H,7H)-dione.

CATO supplies 2,5,8-Trimethylimidazo[1,2-a]pyrazine-3,6(5H,7H)-dione (CAS 194666-10-9), a certified reference material (molecular formula C9H11N3O2, MW 193.20 g/mol) for analytical method development and quality control.

Based on its molecular formula C9H11N3O2, 2,5,8-Trimethylimidazo[1,2-a]pyrazine-3,6(5H,7H)-dione contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 193.20 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
