Chemical Structure

Ammonium dimolybdate CAS 27546-07-2 chemical structure

Description

The occurrence of Ammonium dimolybdate is closely related to an inorganic composition in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Ammonium dimolybdate (CAS 27546-07-2), molecular formula MoH4NO and molecular weight 129.99 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Ammonium dimolybdate (MoH4NO) is characterized by an inorganic composition. 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.

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.
