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.[1] Its ability to inhibit corrosion of 6082 wrought aluminum alloy has been studied in NaCl solution of chlorosulfonic acid.[2]

Application

Sodium molybdate dihydrate may be used to:
  • Prepare the modified Luria broth for growing Methylobacterium extorquens AM1 cells.[3]
  • Prepare shuttle-like barium molybdate (BaMoO4) microstructures under microwave conditions.[4]
  • Synthesize nickel-molybdenum-zinc (NiMoZn) electrode.[5]

Features and Benefits

Meets A.C.S. reagent specifications.
