N-(3-Fluorophenyl)-1-(pyridin-4-yl)-3,4-dihydropyrrolo[1,2-a]pyrazine-2(1H)-carbothioamide CAS 393832-62-7

Description

N-(3-Fluorophenyl)-1-(pyridin-4-yl)-3,4-dihydropyrrolo[1,2-a]pyrazine-2(1H)-carbothioamide (CAS 393832-62-7), molecular formula C19H17FN4S and molecular weight 352.43 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution, N-(3-Fluorophenyl)-1-(pyridin-4-yl)-3,4-dihydropyrrolo[1,2-a]pyrazine-2(1H)-carbothioamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 352.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
