Chemical Structure
Description
4-Acetamidophenyl 4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}benzene-1-sulfonate (CAS 338400-17-2) is a high-purity analytical reference standard with the molecular formula C20H14ClF3N2O5S and a molecular weight of 486.85 g/mol.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 4-Acetamidophenyl 4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}benzene-1-sulfonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 486.85 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
CATO manufactures 4-Acetamidophenyl 4-{[3-chloro-5-(trifluoromethyl)pyridin-2-yl]oxy}benzene-1-sulfonate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
