Chemical Structure
Description
The molecular framework of 4-((2-Hydroxypropyl)thio)-2-methylpyrimidin-5-ol (C8H12N2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, 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 supplies 4-((2-Hydroxypropyl)thio)-2-methylpyrimidin-5-ol (CAS 91036-39-4), a certified reference material (molecular formula C8H12N2O2S, MW 200.26 g/mol) for analytical method development and quality control.
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.
As a certified reference material (CRM), 4-((2-Hydroxypropyl)thio)-2-methylpyrimidin-5-ol 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.
