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 4-Hydroxy-5-phenyl-1H-pyrimidin-6-one.
4-Hydroxy-5-phenyl-1H-pyrimidin-6-one (CAS 18337-64-9) is a high-purity analytical reference standard with the molecular formula C10H8N2O2 and a molecular weight of 188.18 g/mol.
The molecular framework of 4-Hydroxy-5-phenyl-1H-pyrimidin-6-one (C10H8N2O2) is characterized by an amino-acid-derived structure, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 4-Hydroxy-5-phenyl-1H-pyrimidin-6-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.
