Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 359.13 g/mol gives 2-[2,6-Dichloro-4-(trifluoromethyl)phenyl]-1,2-dihydrophthalazin-1-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 2-[2,6-Dichloro-4-(trifluoromethyl)phenyl]-1,2-dihydrophthalazin-1-one (CAS 866048-84-2), a certified reference material (molecular formula C15H7Cl2F3N2O, MW 359.13 g/mol) for analytical method development and quality control.
The molecular framework of 2-[2,6-Dichloro-4-(trifluoromethyl)phenyl]-1,2-dihydrophthalazin-1-one (C15H7Cl2F3N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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.
