Chemical Structure
Description
The occurrence of 4-Fluoro-3-methyl-o-phenylenediamine is closely related to a nitrile group, fluorine substitution, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
4-Fluoro-3-methyl-o-phenylenediamine (CAS 485832-95-9) is a high-purity analytical reference standard with the molecular formula C7H9FN2 and a molecular weight of 140.16 g/mol.
4-Fluoro-3-methyl-o-phenylenediamine (C7H9FN2) contains a nitrile group, fluorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
