Chemical Structure
Description
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.
CATO supplies 4-[2-(2-Chlorophenyl)-1,3-thiazol-5-yl]pyrimidin-2-amine (CAS 1823183-79-4), a certified reference material (molecular formula C13H9ClN4S, MW 288.76 g/mol) for analytical method development and quality control.
4-[2-(2-Chlorophenyl)-1,3-thiazol-5-yl]pyrimidin-2-amine (C13H9ClN4S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
