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.
N-(6-Nitro-3-(1H-pyrrolo[2,3-c]pyridin-1-yl)isoquinolin-5-yl)acetamide (CAS 1841444-07-2) is a high-purity analytical reference standard with the molecular formula C18H13N5O3 and a molecular weight of 347.33 g/mol.
Structurally, N-(6-Nitro-3-(1H-pyrrolo[2,3-c]pyridin-1-yl)isoquinolin-5-yl)acetamide (C18H13N5O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 347.33 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.
