Chemical Structure

1-Methyl-5-phenylpyrazin-2(1H)-one CAS 78174-93-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 186.21 g/mol gives 1-Methyl-5-phenylpyrazin-2(1H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-Methyl-5-phenylpyrazin-2(1H)-one (CAS 78174-93-3), a certified reference material (molecular formula C11H10N2O, MW 186.21 g/mol) for analytical method development and quality control.

The molecular framework of 1-Methyl-5-phenylpyrazin-2(1H)-one (C11H10N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO manufactures 1-Methyl-5-phenylpyrazin-2(1H)-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.
