Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Nickel(II) sulfate heptahydrate.
Nickel(II) sulfate heptahydrate (CAS 10101-98-1) is a high-purity analytical reference standard with the molecular formula O4SNiH2O and a molecular weight of 172.76 g/mol.
The molecular framework of Nickel(II) sulfate heptahydrate (O4SNiH2O) is characterized by a sulfone group. 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.
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.
