Urea - Organic Nitrogen

Product Overview

Urea - Organic Nitrogen, also known as Carbamide or Carbonyl diamide, is a colorless crystalline organic compound with the chemical formula CO(NH₂)₂. It serves as a high-purity nitrogen source and plays a central role in the nitrogen cycle, making it foundational for agricultural and industrial applications. This material is supplied as a white crystalline solid with an odorless profile, designed for precise dosing in formulations and processes requiring reliable nitrogen delivery. Its molecular weight is 60.06 g/mol, and its density at 25°C is 1.335 g/mL, supporting predictable handling characteristics across packaging and transport. In fertilizer production, urea provides a rapidly available nitrogen source, while in chemical synthesis it acts as a versatile precursor for functionalized compounds.

In addition to agricultural uses, Urea - Organic Nitrogen is employed in laboratory and industrial settings as a nitrogen source for microbial culture media, biochemical assays, and resin production workflows. The product is manufactured to stringent purity specifications and is ICP-MS/OES tested to limit trace metals, aligning with ACS Reagent Grade and USP-NF Monograph standards. Its controlled moisture uptake, low residue on ignition, and excellent solubility in water ensure consistent performance in fertilizer formulations, feed applications, and chemical syntheses. This combination of purity, reliability, and trace-metal control supports compliant manufacturing and safe, scalable deployment across sectors.

Safety Precautions

Store in a cool, dry place away from moisture and incompatible materials. Use containers made of HDPE or glass to prevent interaction, and avoid exposure to high temperatures and direct sunlight. Ensure proper ventilation during handling and wear appropriate PPE including gloves and safety goggles to minimize contact and inhalation risk. The product should be kept sealed when not in use to preserve solubility characteristics and purity.

In case of exposure, follow standard SDS guidance: although not classified as hazardous, use standard spill response procedures for solids, evacuate the area if dust generation occurs, and avoid creating aerosols. For emergencies, consult the SDS—UN 2811 guidance applies to transport of this material as a non-hazardous solid in typical packaging—seek medical attention if any symptoms arise and report to appropriate authorities as needed.
