Chemical Structure

Nickel(II) bromide hexahydrate CAS 18721-96-5 chemical structure

Description

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.

Nickel(II) bromide hexahydrate (CAS 18721-96-5) is a high-purity analytical reference standard with the molecular formula Br2NiH2O and a molecular weight of 236.52 g/mol.

Structurally, Nickel(II) bromide hexahydrate (Br2NiH2O) contains bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 236.52 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.

As a certified reference material (CRM), Nickel(II) bromide hexahydrate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
