Calcium cyanamide

Calcium cyanamide (CAS 156-62-7, EC 205-861-8, formula CH2N2.Ca) is an inorganic nitrogen compound commercially known under trade names including Nitrolim and Alzodef, and abbreviated as CCC. It carries no E-code designation and is classified under HS code 31029010 within the Salts & Minerals category.

In agriculture, calcium cyanamide functions as a nitrogenous fertilizer and soil-applied biocide: it hydrolyzes in moist soil to release cyanamide, which suppresses weed germination and soil-borne pathogens before converting to plant-available urea. In mining and metals processing, it serves as a reducing agent and desulfurization additive in steel production, reacting directly with sulfur impurities in molten metal.

Calcium cyanamide is supplied in powder form and is subject to REACH registration requirements for EU procurement. Buyers should confirm technical-grade purity specifications and SDS compliance prior to ordering, as the substance is classified as hazardous under CLP regulation.
