Bis(cyclopentadiene)nickel(II) CAS 1271-28-9

Description

Compared with other compounds in its class, the molecular weight of 123.79 g/mol gives Bis(cyclopentadiene)nickel(II) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Bis(cyclopentadiene)nickel(II) (CAS 1271-28-9), a certified reference material (molecular formula C5H5Ni, MW 123.79 g/mol) for analytical method development and quality control.

Structurally, Bis(cyclopentadiene)nickel(II) (C5H5Ni) contains an organic framework. The molecule exhibits a degree of unsaturation (DBE) of 3.5, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 123.79 g/mol, it falls into the low-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.
