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.
2-(4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}phenyl)-4-(thiophen-2-yl)pyrimidine (CAS 477862-43-4), molecular formula C20H11ClF3N3OS and molecular weight 433.83 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}phenyl)-4-(thiophen-2-yl)pyrimidine (C20H11ClF3N3OS) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
