Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1-(4-((4-Bromophenyl)thio)-3-nitrophenyl)-N-(3-chloro-4-fluorophenyl)methanimine (CAS 301193-50-0), a certified reference material (molecular formula C19H11BrClFN2O2S, MW 465.72 g/mol) for analytical method development and quality control.
The molecular framework of 1-(4-((4-Bromophenyl)thio)-3-nitrophenyl)-N-(3-chloro-4-fluorophenyl)methanimine (C19H11BrClFN2O2S) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine/bromine 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.
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.
