Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(6-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}pyridin-2-yl)-1-(4-chlorophenyl)urea.
3-(6-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}pyridin-2-yl)-1-(4-chlorophenyl)urea (CAS 477864-66-7) is a high-purity analytical reference standard with the molecular formula C18H12Cl2F3N5O and a molecular weight of 442.22 g/mol.
3-(6-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]amino}pyridin-2-yl)-1-(4-chlorophenyl)urea (C18H12Cl2F3N5O) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. Halogen substitution raises its density and boiling point; 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.
