Chemical Structure
Description
The occurrence of Triammonium molybdophosphate is closely related to a phosphate ester group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Triammonium molybdophosphate (CAS 12026-66-3) is a high-purity analytical reference standard with the molecular formula MoO3O4PH4N and a molecular weight of 256.96 g/mol.
Based on its molecular formula MoO3O4PH4N, Triammonium molybdophosphate contains a phosphate ester group; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 256.96 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.
As a certified reference material (CRM), Triammonium molybdophosphate 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.
