Trichlorobenzene

Trichlorobenzene (TCB) may refer to any of three isomeric chlorinated derivatives of benzene with the molecular formula C6H3Cl3.[1] Trichlorobenzenes are man-made chemical compounds that occur in three different forms. Even though the forms have the same molecular weight and molecular formulae, they are structurally different by the positions of the chlorine atoms attached to the benzene ring. 1,2,3-Trichlorobenzene and 1,3,5-trichlorobenzene are colorless solids, but 1,2,4-trichlorobenzene is a colorless oil. The isomers may also have different chemical and toxicological properties.[2][3]

1,2,3-Trichlorobenzene
1,2,4-Trichlorobenzene
1,3,5-Trichlorobenzene

gollark: SQLite is open source, you see.
gollark: I have offsite backups of some data, I think ABR's stuff is in there.
gollark: Ah, but I have a *spare* drive right next to it with backups.
gollark: Unlikely, SQLite is very robust, and I have backups.
gollark: I think the most likely scenario is that I lose my data and backup disk.
