Chemical Structure

(SP-4-1)-Nickel(II) acetate CAS 20998-57-6 chemical structure

Description

(SP-4-1)-Nickel(II) acetate (CAS 20998-57-6), molecular formula C2H3O2Ni and molecular weight 117.74 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (SP-4-1)-Nickel(II) acetate (C2H3O2Ni) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.

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.

As a certified reference material (CRM), (SP-4-1)-Nickel(II) acetate 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.
