Description

Magnesium Chromate CAS NO 13423-61-5 is an inorganic salt composed of magnesium and chromate ions. This compound is valued in industrial processes for its role as a corrosion inhibitor and a source of chromate ions. It is primarily utilized in sectors such as metal surface treatment, specialty pigment formulation, and as a chemical intermediate in research and development.

Application

• Corrosion Inhibition: Used in formulations for protective coatings and conversion coatings on metals like aluminum and magnesium alloys.
• Pigment and Dye Intermediate: Serves as a precursor or additive in the manufacture of certain yellow-orange inorganic pigments.
• Chemical Synthesis: Acts as a reagent or catalyst in specific organic and inorganic synthesis reactions within R&D laboratories.
• Wood Preservation: Historically used in certain wood treatment formulations, though its use is now highly restricted.
• Analytical Chemistry: Employed as a standard or reagent in specific quantitative analytical methods.

Quality Control

Our Magnesium Chromate is produced and tested under a stringent quality management system. Each batch undergoes comprehensive analysis to ensure it meets precise chemical and physical specifications. A Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with every shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture. Observe all local regulations for the storage of chromium(VI) compounds.
