Description

Palladium On Calcium Carbonate Moistened With Water, 5% Pd, Unreduced is a heterogeneous catalyst consisting of finely dispersed palladium metal supported on a calcium carbonate carrier, supplied in a moistened, unreduced form. This product is engineered to provide a highly active and selective catalytic surface for a wide range of hydrogenation and coupling reactions in chemical synthesis. It is an essential material for R&D laboratories and production facilities in the pharmaceutical, fine chemical, and agrochemical industries seeking efficient and reliable catalytic performance.

Application

• Selective Hydrogenation Reactions: Used for the reduction of alkynes to alkenes (semi-hydrogenation), nitro groups to amines, and dehalogenation processes.
• Pharmaceutical Intermediate Synthesis: A key catalyst in the production of active pharmaceutical ingredients (APIs) and complex drug molecules.
• Fine Chemical Manufacturing: Facilitates coupling reactions like Suzuki, Heck, and Sonogashira for constructing complex organic frameworks.
• Agrochemical Production: Employed in the synthesis of herbicides, pesticides, and plant growth regulators.
• Research & Development: Serves as a versatile catalyst for method development and exploratory synthesis in academic and industrial labs.
• Fragrance and Flavor Synthesis: Used in the hydrogenation steps to create key aroma chemicals and flavoring agents.

Quality Control

Our Palladium On Calcium Carbonate catalyst is manufactured under strict quality protocols to ensure batch-to-batch consistency and optimal catalytic activity. Each lot is tested for critical parameters including palladium content, moisture level, and particle size distribution. A comprehensive Certificate of Analysis (COA) detailing these specifications is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This material is moisture-sensitive (hygroscopic) and should be kept sealed to prevent drying out or contamination. Keep away from strong acids and oxidizing agents.
