Description

Chromium Nitrate CAS NO 17135-66-9 is an inorganic salt of chromium, widely utilized as a precursor for chromium-based catalysts and functional materials. Its primary commercial value lies in its role as a source of trivalent chromium ions for applications requiring controlled oxidation states and specific material properties. This compound is essential for manufacturers and R&D facilities in the chemical synthesis, catalyst production, and specialty ceramics industries.

Application

• Catalyst precursor for organic synthesis and petroleum refining processes.
• Key raw material in the manufacture of chromium oxide pigments and ceramic glazes.
• Used in surface treatment and conversion coatings for corrosion resistance on metals.
• Essential component in the preparation of specialized catalysts for dehydrogenation and polymerization reactions.
• Employed in laboratory research as a standard source of Cr(III) ions for analytical chemistry and material science.
• Used in the synthesis of other chromium compounds and coordination complexes.

Quality Control

Our Chromium Nitrate is produced under stringent quality management systems to ensure batch-to-batch consistency and reliability. The product undergoes comprehensive analytical testing, including assay, impurity profiling, and physical characterization, to meet exacting industry standards. A Certificate of Analysis (COA) detailing purity, heavy metal content, and other critical parameters is provided with every shipment to guarantee compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Due to its hygroscopic and easily oxidized nature, the container must be kept tightly sealed to exclude moisture and is best stored under an inert atmosphere for long-term stability. Keep away from incompatible materials such as strong reducing agents and organic substances.
