Description
This heading encompasses a broad range of chemical compounds primarily characterized as ethers, ether-alcohols, ether-phenols, ether-alcohol-phenols, as well as several types of peroxides including alcohol peroxides, ether peroxides, acetal and hemiacetal peroxides, and ketone peroxides. It also includes their halogenated, sulfonated, nitrated, or nitrosated derivatives regardless of whether they are chemically defined or not.
These substances find diverse applications in industrial, pharmaceutical, and chemical manufacturing sectors. The heading classifies compounds based on their chemical structure and functional groups, as well as specific derivatives and modifications.
