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 1040689-27-7 4-(Benzyloxy)-N-(4-fluorobenzyl)aniline 7907AC C20H18FNO (CAS 1040689-27-7), a certified reference material (molecular formula C20H18FNO, MW 307.36 g/mol) for analytical method development and quality control.
The molecular framework of 1040689-27-7 4-(Benzyloxy)-N-(4-fluorobenzyl)aniline 7907AC C20H18FNO (C20H18FNO) is characterized by a steroid core, an amide 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
