Usage

General Description

ALPHA,ALPHA,ALPHA,ALPHA',ALPHA',ALPHA'-HEXACHLORO-M-XYLENE is a chemical compound with the molecular formula C8H4Cl6. It is a member of the xylene family, which are aromatic hydrocarbons with a central benzene ring and two methyl groups. This particular compound is highly chlorinated, with six chlorine atoms attached to the xylene molecule. It is primarily used as a pesticide and insecticide, as well as in the manufacturing of other chemicals. Due to its toxicity and potential for environmental harm, its use is heavily regulated and restricted in many countries. Exposure to ALPHA,ALPHA,ALPHA,ALPHA',ALPHA',ALPHA'-HEXACHLORO-M-XYLENE can have serious health effects, including damage to the nervous and reproductive systems, as well as potential carcinogenic properties.
