Chemical Structure
Description
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.
1-Isobutyl-1H-imidazo[4,5-c][1,5]naphthyridin-4-amine ethanesulfonate (CAS 885483-02-3), molecular formula C13H15N5C2H6O3S and molecular weight 351.43 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Isobutyl-1H-imidazo[4,5-c][1,5]naphthyridin-4-amine ethanesulfonate (C13H15N5C2H6O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 351.43 g/mol, it falls into the moderately-high-molecular-weight range. 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).
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.
