CATO supplies 2-(4-Fluorophenylamino)naphtho[2,3-d]thiazole-4,9-dione (CAS 220333-06-2), a certified reference material (molecular formula C17H9FN2O2S, MW 324.33 g/mol) for analytical method development and quality control.
The molecular framework of 2-(4-Fluorophenylamino)naphtho[2,3-d]thiazole-4,9-dione (C17H9FN2O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
