Sodium molybdate dihydrate Usage And Synthesis

Chemical Properties

white crystals or powder

Uses

Sodium molybdate dihydrate has been used as one of the phosphatase inhibitor during the Western blot analysis.
It may be used to prepare:

• Shuttle-like barium molybdate (BaMoO₄) microstructures under microwave conditions.
• Nickel-molybdenum-zinc (NiMoZn) electrode.
• Eu³⁺ doped lead molybdate (PbMoO₄) nanocrystals (NCs) under microwave conditions.

Uses

Sodium molybdate dihydrate may be used to:

• Prepare the modified Luria broth for growing Methylobacterium extorquens AM1 cells.
• Prepare shuttle-like barium molybdate (BaMoO₄) microstructures under microwave conditions.
• Synthesize nickel-molybdenum-zinc (NiMoZn) electrode.

Uses

Sodium molybdate dihydrate can be used to manufacture inorganic and organic pigments, corrosion inhibitor, bath additive for metals finishing, reagent for alkaloids, micronutrient for plants and animals.

Definition

ChEBI: Sodium molybdate dihydrate is a hydrate that is the dihydrate form of sodium molybdate. It has a role as a poison. It is a hydrate, an inorganic sodium salt and a molybdate. It contains a sodium molybdate (anhydrous).

General Description

Sodium molybdate dihydrate (Na₂MoO₄.2H₂O) is basic in nature. Its crystals belong to the orthorhombic crystal system and space group Pbca.

Hazard

Sodium molybdate dihydrate is toxic to humans and irritating to eyes and skin. Causes somnolence and coma in intraperitoneal lethal-dose studies of mice and rats; Causes normocytic anemia in 4-week intermittent intraperitoneal studies of rats; Causes urine changes, pigmented or nucleated red blood cells, changes in teeth or supporting structures, weight loss, effects on testes, epididymis, or sperm duct, lactation, and effects on menstrual cycle in repeated-dose oral studies of rats.

Purification Methods

Crystallise it from hot water (1mL/g) by cooling to 0o.
