Chemical Structure
Description
N’-(7-Fluoropyrrolo[1,2-a]quinoxalin-4-yl)pyrazine-2-carbohydrazide Hydrochloride (CAS 917497-70-2), molecular formula C16H11FN6OHCl and molecular weight 358.76 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, N’-(7-Fluoropyrrolo[1,2-a]quinoxalin-4-yl)pyrazine-2-carbohydrazide Hydrochloride is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 358.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
