Chemical Structure
Description
The occurrence of 5-Bromo-4-((2,4-dichlorobenzyl)thio)-2-(methylthio)pyrimidine is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Bromo-4-((2,4-dichlorobenzyl)thio)-2-(methylthio)pyrimidine (CAS 6341-65-7), a certified reference material (molecular formula C25H22O12, MW 514.43 g/mol) for analytical method development and quality control.
5-Bromo-4-((2,4-dichlorobenzyl)thio)-2-(methylthio)pyrimidine (C25H22O12) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
