Urea is an organic compound with the chemical formula CO(NH₂)₂. It is a colorless, odorless solid, highly soluble in water, and practically non-toxic. Here are some key points about urea:
Chemical Properties:
- Formula: CO(NH₂)₂
- Molecular Weight: 60.06 g/mol
- Structure: Urea consists of two amine groups (-NH₂) attached to a carbonyl group (C=O).
Production:
Urea is primarily produced via the Haber-Bosch process, which synthesizes ammonia from nitrogen and hydrogen. The ammonia is then combined with carbon dioxide to form urea: 2NH3+CO2→CO(NH2)2+H2O2 text{NH}_3 + text{CO}_2 rightarrow text{CO(NH}_2text{)}_2 + text{H}_2text{O}2NH3+CO2→CO(NH2)2+H2O

ToggleUses of Urea
Protein Denaturation and Renaturation:
- Protein Denaturation: Urea is often used in the process of protein denaturation. High concentrations of urea can disrupt hydrogen bonds in proteins, leading to the unfolding of their secondary and tertiary structures.
- Protein Renaturation: After denaturation, urea can be gradually removed (by dialysis or dilution), allowing the protein to refold into its native structure. This is crucial in studies of protein folding and structure.
Buffering Agent:
- Buffers: Urea can be used as a buffering agent in electrophoresis and other biochemical assays to maintain a stable pH and provide a consistent ionic environment.
Gel Electrophoresis:
- PAGE (Polyacrylamide Gel Electrophoresis): Urea is used in denaturing polyacrylamide gel electrophoresis (PAGE) to separate nucleic acids or proteins by size. The denaturing properties of urea ensure that the biomolecules are in their unfolded state, providing more accurate size-based separation.
Chemical Synthesis:
- Synthesis of Organic Compounds: Urea serves as a reactant or catalyst in various organic synthesis reactions, including the synthesis of heterocyclic compounds and the formation of urea derivatives.
Protein Crystallization:
- Crystallization Studies: Urea is used in protein crystallization experiments to help understand protein structures. It can influence the solubility and crystallization conditions of proteins.
Molecular Biology:
- RNA Folding Studies: Urea is used to denature RNA, allowing researchers to study RNA folding and structure.
- Hybridization Studies: Urea can destabilize double-stranded nucleic acids, which is useful in hybridization studies involving DNA and RNA.
Clinical Chemistry:
- Blood Urea Nitrogen (BUN) Test: Urea is used in assays to measure the concentration of urea nitrogen in the blood, which is an important indicator of kidney function.
Research on Enzymatic Reactions:
- Enzyme Activity Studies: Urea can be used to study the effects of denaturants on enzyme activity, helping to elucidate the mechanisms of enzyme action and stability.
Stabilization of Biological Samples:
- Stabilizing Proteins and Nucleic Acids: Urea is sometimes used to stabilize proteins and nucleic acids during storage and handling in the laboratory.

Aluminum Carbonate 250g
Aluminum carbonate is a chemical compound with the formula Al2(CO3)3. It is a white, crystalline solid that is insoluble in water. Aluminum carbonate is not commonly encountered in pure form due to its high instability, especially in the presence of water and carbon dioxide. Instead, it tends to decompose into aluminum hydroxide and carbon dioxide when exposed to moisture or acidic conditions.
Aluminum Oxide 500 grams
Aluminum oxide, often referred to as alumina, is a chemical compound made up of aluminum and oxygen atoms (Al2O3). It occurs naturally in various minerals, including corundum and bauxite. It is one of the most widely used compounds, valued for its hardness, strength, and resistance to abrasion and corrosion.
Aluminum Sulphate 500gm
Aluminum sulfate, also known as alum, is a chemical compound with the formula Al2(SO4)3. It's commonly used in water treatment plants as a coagulant to clarify turbid or muddy water by causing suspended particles to clump together and settle out. In addition to water treatment, aluminum sulfate has various other industrial applications, such as in paper manufacturing, dyeing, and as a mordant in textile dyeing to help fix dyes to fabrics.
Ammonium Oxalate 500gm
Anhydrous Aluminum Chloride
Anhydrous aluminum chloride, often represented as AlCl3, is a chemical compound composed of aluminum and chlorine. "Anhydrous" means it lacks water molecules in its structure. It's a white or pale yellow solid that is highly hygroscopic, meaning it readily absorbs moisture from the air. This property makes handling it a bit tricky since it can form a solution with water vapor in the air, turning into a fuming liquid.
