Chemical Structure

1-Methyl-1H-pyrimidin-2-one CAS 3739-81-9 chemical structure

Description

1-Methyl-1H-pyrimidin-2-one (CAS 3739-81-9), molecular formula C5H6N2O and molecular weight 110.11 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 1-Methyl-1H-pyrimidin-2-one (C5H6N2O) is characterized by an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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.

CATO manufactures 1-Methyl-1H-pyrimidin-2-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
