Chemical Structure
Description
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.
CATO supplies (SP-4-2)-[4,4′-bis(1,1-dimethylethyl)-2,2′-bipyridine-κN1,κN1′]dibromo-Nickel (CAS 1894189-67-3), a certified reference material (molecular formula C18H24Br2N2Ni, MW 486.90 g/mol) for analytical method development and quality control.
Structurally, (SP-4-2)-[4,4′-bis(1,1-dimethylethyl)-2,2′-bipyridine-κN1,κN1′]dibromo-Nickel (C18H24Br2N2Ni) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 486.90 g/mol, it falls into the moderately-high-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.
