Chemical Structure
Description
CATO supplies 4-(2,3-Difluorophenyl)-2-hydrazono-2,3-dihydrothiazole (CAS 886495-05-2), a certified reference material (molecular formula C9H7F2N3S, MW 227.23 g/mol) for analytical method development and quality control.
Structurally, 4-(2,3-Difluorophenyl)-2-hydrazono-2,3-dihydrothiazole (C9H7F2N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 227.23 g/mol, it falls into the medium-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.
