CATO supplies (E)-2-chloro-1-(5-((2-(2-chlorophenyl)hydrazono)methyl)-1H-pyrrol-3-yl)ethan-1-one (CAS 866142-95-2), a certified reference material (molecular formula C13H11Cl2N3O, MW 296.15 g/mol) for analytical method development and quality control.
Structurally, (E)-2-chloro-1-(5-((2-(2-chlorophenyl)hydrazono)methyl)-1H-pyrrol-3-yl)ethan-1-one (C13H11Cl2N3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 296.15 g/mol, it falls into the medium-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
