Description

Compared with other compounds in its class, the molecular weight of 158.17 g/mol gives (7S,8aR)-7-fluorohexahydropyrrolo[1,2-a]pyrazin-3(4H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(7S,8aR)-7-fluorohexahydropyrrolo[1,2-a]pyrazin-3(4H)-one (CAS 2165789-76-2), molecular formula C7H11FN2O and molecular weight 158.17 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amide group, a hydroxyl group, an ether linkage, fluorine substitution, (7S,8aR)-7-fluorohexahydropyrrolo[1,2-a]pyrazin-3(4H)-one is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 158.17 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.
