Urea - Organic Nitrogen

Product Overview

Urea - Organic Nitrogen (CAS 57-13-6), also known as Carbamide, is a high-purity crystalline organic compound utilized as a primary nitrogen source in agricultural and industrial applications. This Technical Grade material exceeds 99.0% assay purity, meeting rigorous standards compatible with ACS Reagent and USP-NF Monograph specifications. It appears as a white, odorless solid with excellent water solubility, designed for precise dosing in formulations.

With a nitrogen content essential for biological and chemical processes, Urea functions as a foundational precursor in the synthesis of resins, plastics, and pharmaceutical intermediates. In agricultural sectors, it serves as a concentrated nitrogen fertilizer and animal feed additive. The product is manufactured with strict control over trace metals and moisture content, ensuring consistent solubility and stability during storage and processing. Its molecular weight of 60.06 g/mol and density of 1.335 g/mL allow for predictable handling in bulk industrial workflows.

• NOx Control: Used in Selective Catalytic Reduction (SCR) systems to reduce emissions.
• Industrial Processing: Dyeing and printing auxiliary in the textile industry.

Safety Precautions

Urea is generally considered stable but should be stored in a cool, dry area to prevent caking due to moisture absorption. Use High-Density Polyethylene (HDPE) or glass containers. Isolate from strong oxidizers, nitrites, and inorganic chlorides.

While not classified as a hazardous shipping material, standard industrial hygiene practices apply. Wear protective gloves, safety goggles, and ensure adequate ventilation to avoid dust inhalation. In the event of a spill, sweep up the solid to prevent slippery surfaces and dispose of in accordance with local regulations. Refer to the Safety Data Sheet (SDS) for detailed handling instructions.
