Chemical Structure
Description
The occurrence of (2-Fluoro-4-methylphenyl)hydrazine 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.
(2-Fluoro-4-methylphenyl)hydrazine (CAS 5596-75-8), molecular formula C7H9FN2 and molecular weight 140.16 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (2-Fluoro-4-methylphenyl)hydrazine (C7H9FN2) contains a nitrile group, fluorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 140.16 g/mol, it falls into the low-molecular-weight range. 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.
