5-Fluoro-2-(pyridin-2-yl)pyrimidin-4(3H)-one CAS 1240596-22-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 5-Fluoro-2-(pyridin-2-yl)pyrimidin-4(3H)-one.

CATO supplies 5-Fluoro-2-(pyridin-2-yl)pyrimidin-4(3H)-one (CAS 1240596-22-8), a certified reference material (molecular formula C9H6FN3O, MW 191.16 g/mol) for analytical method development and quality control.

Structurally, 5-Fluoro-2-(pyridin-2-yl)pyrimidin-4(3H)-one (C9H6FN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. 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 191.16 g/mol, it falls into the medium-molecular-weight range. 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.

As a certified reference material (CRM), 5-Fluoro-2-(pyridin-2-yl)pyrimidin-4(3H)-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
