Chemical Structure
Description
5-(2-Hydroxyethyl)-6-methyl-2-(methylthio)pyrimidin-4-ol (CAS 98489-83-9) is a high-purity analytical reference standard with the molecular formula C8H12N2O2S and a molecular weight of 200.26 g/mol.
5-(2-Hydroxyethyl)-6-methyl-2-(methylthio)pyrimidin-4-ol (C8H12N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 5-(2-Hydroxyethyl)-6-methyl-2-(methylthio)pyrimidin-4-ol 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.
