Chemical Structure
Description
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.
6-(Tert-butyl)-2-(methylthio)pyrimidin-4-ol (CAS 66698-63-3), molecular formula C9H14N2OS and molecular weight 198.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-(Tert-butyl)-2-(methylthio)pyrimidin-4-ol (C9H14N2OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO manufactures 6-(Tert-butyl)-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.
