Chemical Structure
Description
2-(2,4-Dichlorophenyl)-2-[6-(phenylsulfanyl)pyridazin-3-yl]acetonitrile (CAS 339026-28-7), molecular formula C18H11Cl2N3S and molecular weight 372.27 g/mol, is a CATO reference standard with documented purity and traceability.
2-(2,4-Dichlorophenyl)-2-[6-(phenylsulfanyl)pyridazin-3-yl]acetonitrile (C18H11Cl2N3S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
