Description

The occurrence of 3,5,8-Trimethyl-3H-imidazo[4,5-f]quinoxalin-2-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.

3,5,8-Trimethyl-3H-imidazo[4,5-f]quinoxalin-2-amine (CAS 103139-94-2), molecular formula C12H13N5 and molecular weight 227.27 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3,5,8-Trimethyl-3H-imidazo[4,5-f]quinoxalin-2-amine (C12H13N5) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 227.27 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.
