Main Applications
Water Treatment Industry:
Serves as a corrosion inhibitor and scale inhibitor in industrial circulating cooling water systems, protecting steel, copper, and other metals, especially in neutral or alkaline environments.
Shows synergistic effects when blended with polyphosphates and zinc salts.
Metal Processing and Surface Treatment:
Used in metal phosphating solutions to improve the adhesion and corrosion resistance of phosphate coatings;
Acts as an etchant and rust inhibitor for aluminum alloys.
Chemical Industry and Catalysts:
Raw material for synthesizing molybdenum-based catalysts (e.g., for acrylonitrile production);
Precursor for other molybdenum compounds (e.g., ammonium molybdate, barium molybdate).
Agriculture and Fertilizers:
Used as a micronutrient fertilizer to supplement molybdenum for plant growth, particularly beneficial for leguminous crops (e.g., soybeans, peanuts).
Pharmaceuticals and Pigments:
Applied in pharmaceuticals for molybdenum-containing drug synthesis;
Component of corrosion-inhibiting pigments in the paint industry.

Safety and Storage
Toxicity:
Low toxicity, but prolonged exposure or inhalation of dust may irritate the respiratory tract and skin;
Ingestion may cause nausea and vomiting-seek medical attention immediately.
Environmental Impact:
Molybdenum is a heavy metal; avoid discharging untreated molybdenum-containing wastewater into water bodies, as it may harm aquatic life.
Storage Requirements:
Store in sealed containers in a dry, ventilated area to prevent deliquescence (especially for the dihydrate);
Keep away from acids and strong oxidizers to avoid reactions;
Transport as a general chemical, handling with care to prevent packaging damage.

Packaging can be customized according to customer requirements.
