Overview
Diethylurea (DEU) is an organic compound belonging to the urea derivative family. It is primarily used as an intermediate in the synthesis of pharmaceuticals, agrochemicals, and specialty polymers. Its chemical stability and solubility in common solvents make it a versatile component in industrial applications. First synthesized in the early 20th century, DEU has gained prominence due to its role in producing high-value chemicals. It is often preferred for its relatively low toxicity and ease of handling compared to other urea derivatives.
Physical and Chemical Properties
Diethylurea appears as a white crystalline solid with a melting point of 70-72°C. It is soluble in water, ethanol, and acetone, which facilitates its use in various chemical processes. The compound is stable under normal temperatures and pressures, with no significant decomposition observed under standard conditions. Its molecular structure features two ethyl groups attached to a urea core, contributing to its moderate polarity and solubility profile. DEU is non-flammable and exhibits low reactivity, making it safe for industrial use with proper precautions.
Main Applications
In the pharmaceutical industry, DEU serves as a key intermediate in the synthesis of drugs, particularly those targeting central nervous system disorders. Its role in agrochemical production includes the formulation of herbicides and pesticides, where it acts as a stabilizer or active ingredient precursor. The polymer industry utilizes DEU as an additive to modify resin properties, enhancing durability and thermal stability. Its compatibility with other chemicals and solvents makes it a preferred choice for specialized formulations.
Safety and Storage
While DEU is considered low in toxicity, proper handling is essential to avoid irritation to the skin, eyes, or respiratory system. Personal protective equipment (PPE) such as gloves and goggles should be worn during handling. Ensure adequate ventilation in workspaces where DEU is processed. Storage recommendations include keeping the compound in a cool, dry environment, away from direct sunlight and moisture. Containers should be tightly sealed to prevent contamination and degradation over time.
B2B Procurement Guide
When procuring DEU, buyers should prioritize suppliers with verified certifications (e.g., ISO, GMP) to ensure product quality and consistency. Key specifications to confirm include purity levels (typically 98% or higher), CAS number (623-76-7), and packaging options (e.g., 25 kg bags or custom quantities). Price negotiations should consider bulk purchase discounts, with reference prices ranging from $20 to $50 per kg. Lead times and logistics support (e.g., cold chain for sensitive shipments) are additional factors to evaluate for seamless supply chain integration.
