Chemical Structure
Description
The occurrence of Ammonium molybdate is closely related to an inorganic composition in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ammonium molybdate (CAS 13106-76-8), molecular formula H2MoO4H3N and molecular weight 178.99 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ammonium molybdate (H2MoO4H3N) 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.
As a certified reference material (CRM), Ammonium molybdate 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.
