Description
As a certified reference material (CRM), 2-(Ethylthio)-5-iodopyrimidin-4(1H)-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.
2-(Ethylthio)-5-iodopyrimidin-4(1H)-one (CAS 76510-62-8) is a high-purity analytical reference standard with the molecular formula C6H7IN2OS and a molecular weight of 282.10 g/mol.
The molecular framework of 2-(Ethylthio)-5-iodopyrimidin-4(1H)-one (C6H7IN2OS) is characterized by an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, iodine substitution, an aromatic ring system. 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
