Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 324.35 g/mol gives N'-(1-(2,5-difluorophenyl)ethylidene)-4-methylbenzenesulfonohydrazide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
N'-(1-(2,5-difluorophenyl)ethylidene)-4-methylbenzenesulfonohydrazide (CAS 1931949-99-3) is a high-purity analytical reference standard with the molecular formula C15H14F2N2O2S and a molecular weight of 324.35 g/mol.
The molecular framework of N'-(1-(2,5-difluorophenyl)ethylidene)-4-methylbenzenesulfonohydrazide (C15H14F2N2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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.
