Description

Calcium Cyanamide CAS NO 156-62-7 is a versatile inorganic compound widely used as a nitrogen fertilizer and a key intermediate in industrial chemical synthesis. Its primary value lies in its dual functionality as a slow-release nitrogen source for agriculture and a crucial reagent for producing nitrogen-containing chemicals. This product is essential for manufacturers in the agrochemical, pharmaceutical, and specialty chemical industries seeking a reliable and effective raw material.

Application

• As a slow-release nitrogen fertilizer and soil conditioner in agriculture.
• As a key intermediate in the production of cyanamide, dicyandiamide, and melamine.
• As a defoliant and herbicide in specific horticultural and agricultural applications.
• In the steel industry as a nitrogen source for nitriding to harden the surface of steel.
• As a stabilizer and vulcanization accelerator in certain rubber manufacturing processes.
• In wastewater treatment for the removal of heavy metals.
• As a precursor in the synthesis of various pharmaceuticals and fine chemicals.

Quality Control

Our Calcium Cyanamide is produced under strict quality management protocols to ensure batch-to-batch consistency and reliability. The product undergoes rigorous analytical testing, including assay and impurity profiling, to meet defined industrial specifications. A Certificate of Analysis (COA) detailing purity, physical characteristics, and safety data is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area away from incompatible materials. Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which can lead to caking and decomposition. Store at room temperature (15-25°C).
