Chlorobenzene is an organic compound with the formula C6H5Cl. It is the result of a hydrogen atom in the benzene ring being replaced by a chlorine atom. The following is a detailed description of the properties, uses, manufacturing methods and safety information of chlorobenzene:
Nature:
- Appearance: colorless liquid or white crystal.
- Boiling point: 131C.
- Density: 1.11g /ml.
- Melting point: -46C.
- Soluble: Soluble in organic solvents such as ethanol and ether, insoluble in water.
Chlorobenzene exists in a variety of isomers, such as o-chlorobenzene, M-chlorobenzene, and P-chlorobenzene.
Purpose:
- Industrial use: chlorobenzene is widely used in organic synthesis reactions and industrial production, and can be used as a solvent, antibacterial agent, flame retardant, insecticide, pickling agent, etc.
- Medical use: chlorobenzene can be used in the synthesis of drugs, fungicides and pesticides.
- Laboratory use: Chlorobenzene can be used as a solvent and reaction intermediate for organic synthesis experiments.
A corrosion inhibitor is a chemical compound or substance designed to mitigate or prevent corrosion, which is the deterioration of materials, particularly metals, due to chemical reactions with their environment. These inhibitors work by forming a protective layer on the metal's surface, blocking or slowing down the corrosion process. Corrosion inhibitors find extensive use in industries such as manufacturing, oil and gas, transportation, and infrastructure to prolong the lifespan of equipment, pipelines, and structures, ultimately saving costs and ensuring safety. They play a crucial role in safeguarding the integrity and functionality of metal components exposed to corrosive conditions, such as moisture, chemicals, or extreme temperatures.

Gel and Clot Activator Tube aims to obtain high quality serum specimen for biochemistry , immunology and serology tests in clinical inspection.
Inside the tube there is some gel present at the bottom, which is a pure substance and is very stable in physico-chemistry properties.
Otherwise, the gel can avoid high- temperature decomposition and small molecules precipitation, hence it greatly reduces the risk of testing equipment clogging.
