Overview

Product description：

Ammonium molybdate can be prepared by dissolving molybdenum trioxide in ammonia.

Application：

Ammonium molybdate has been used to prepare molybdenum phosphate. (NH4) 2MoO4 is used as an analytical reagent for quantitative analysis of aqueous solutions of phosphates, silicates, arsenates, and lead. Saturated concentration of (NH4) 2MoO4 is used for low-temperature negative staining and as a negative staining agent for biological electron microscopy. Ammonium molybdate is used to study the crystallization of cell-free membrane proteins.
