Toluene diisocyanate

Description:

Toluene diisocyanate (TDI) is an aromatic isocyanate commonly used in the production of flexible polyurethane foams, coatings, and adhesives. It is characterized by its two isocyanate functional groups, which make it highly reactive, particularly with compounds containing hydroxyl or amine groups. TDI is typically a colorless to pale yellow liquid with a distinctive odor, and it has a relatively low boiling point. It is soluble in organic solvents but has limited solubility in water. Due to its reactivity, TDI can pose health risks, including respiratory irritation and sensitization, making proper handling and safety precautions essential during its use. Additionally, TDI is classified as a hazardous substance, and exposure limits are regulated in many countries. Its applications extend beyond foams to include elastomers and sealants, highlighting its versatility in various industrial processes. Overall, TDI is a crucial chemical in the polymer industry, but its handling requires careful attention to safety protocols to mitigate potential health risks.

Tolylene diisocyanate

CAS: 26471-62-5

Tolylene diisocyanate is a model system for the study of high resistance. It is an organic compound that is used as a substrate film for the polymerase chain reaction (PCR). The reaction solution contains toluene and electrochemical impedance spectroscopy (EIS) is used to measure the current in order to determine the rate of reaction. Tolylene diisocyanate has been shown to be carcinogenic in laboratory animals, though it has not been found to cause cancer in humans. This chemical can be detected in human serum by solid phase microextraction (SPME) and analytical methods such as gas chromatography-mass spectrometry and liquid chromatography-mass spectrometry.
