Chemical Structure
Description
Owing to an inorganic composition, Ammonium Molybdate Tetrahydrate is typically white to off-white amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 1091.68 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Ammonium Molybdate Tetrahydrate (CAS 12054-85-2), molecular formula Mo7O24H4NH2O and molecular weight 1091.68 g/mol, is a CATO reference standard with documented purity and traceability.
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.
