Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[2-(Pyrazin-2-yl)-1H-imidazol-1-yl]ethan-1-amine.
2-[2-(Pyrazin-2-yl)-1H-imidazol-1-yl]ethan-1-amine (CAS 2097937-27-2) is a high-purity analytical reference standard with the molecular formula C9H11N5 and a molecular weight of 189.22 g/mol.
Structurally, 2-[2-(Pyrazin-2-yl)-1H-imidazol-1-yl]ethan-1-amine (C9H11N5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 189.22 g/mol, it falls into the medium-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
