Description

General description

Sodium molybdate dihydrate (SMD) is a molybdic acid disodium salt. Its toxic effect on the avian species, northern bobwhite quail has been investigated. Its ability to inhibit corrosion of 6082 wrought aluminum alloy has been studied in NaCl solution of chlorosulfonic acid.

Application

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.

Features and Benefits

Meets A.C.S. reagent specifications.
