Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Mercury nitrate dihydrate.
Mercury nitrate dihydrate (CAS 7782-86-7) is a high-purity analytical reference standard with the molecular formula HgNO3H2O and a molecular weight of 280.61 g/mol.
Based on its molecular formula HgNO3H2O, Mercury nitrate dihydrate contains an inorganic composition; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 280.61 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
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.
