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.
[Hydrotris(3,4,5-tribromo-1H-pyrazolato-κN1)borato(1-)-κN2,κN2′,κN2′′]-silver (CAS 1190321-32-4) is a high-purity analytical reference standard with the molecular formula C9HAgBBr9N6 and a molecular weight of 1030.96 g/mol.
The molecular framework of [Hydrotris(3,4,5-tribromo-1H-pyrazolato-κN1)borato(1-)-κN2,κN2′,κN2′′]-silver (C9HAgBBr9N6) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
