Chemical Structure
Description
2,6-Difluorophenyl-N-Tert-Butylnitrone (CAS 134152-13-9), molecular formula C11H14F2NO and molecular weight 214.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,6-Difluorophenyl-N-Tert-Butylnitrone (C11H14F2NO) is characterized by a nitrogen-containing heterocyclic scaffold, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
