6-((5-Chloro-3-methylbenzofuran-2-yl)thio)pyridazin-3(2H)-one CAS 463976-10-5

Description

6-((5-Chloro-3-methylbenzofuran-2-yl)thio)pyridazin-3(2H)-one (CAS 463976-10-5), molecular formula C13H9ClN2O2S and molecular weight 292.74 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 6-((5-Chloro-3-methylbenzofuran-2-yl)thio)pyridazin-3(2H)-one (C13H9ClN2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 292.74 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.

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.

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.
