5-Imino-2,3-dimethyl-5H-pyrrolo[3,4-b]pyrazin-7-amine CAS 55408-62-3

Description

The occurrence of 5-Imino-2,3-dimethyl-5H-pyrrolo[3,4-b]pyrazin-7-amine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Imino-2,3-dimethyl-5H-pyrrolo[3,4-b]pyrazin-7-amine (CAS 55408-62-3), molecular formula C8H9N5 and molecular weight 175.19 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 5-Imino-2,3-dimethyl-5H-pyrrolo[3,4-b]pyrazin-7-amine (C8H9N5) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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).

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.
