Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
6-Chloro-2-(trifluoromethyl)imidazo[1,2-b]pyridazine-3-sulfonamide (CAS 570416-53-4), molecular formula C7H4ClF3N4O2S and molecular weight 300.65 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 6-Chloro-2-(trifluoromethyl)imidazo[1,2-b]pyridazine-3-sulfonamide (C7H4ClF3N4O2S) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 300.65 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
