FAQ

Frequently Asked Questions

Yes, it is toxic if ingested or inhaled in significant quantities and is a potential carcinogen. Its use is regulated.

Para-dichlorobenzene has a strong, sweet, and pungent odour characteristic of mothballs.

They are ortho-dichlorobenzene (1,2-), meta-dichlorobenzene (1,3-), and para-dichlorobenzene (1,4-), differing in the relative positions of the chlorine atoms on the benzene ring.

While both have been used as moth repellents, they are chemically distinct. Para-dichlorobenzene is now more common, and naphthalene use has declined due to flammability and toxicity concerns.
