• PhenolRelated: Coal tar was an early commercial source of phenol.

• Polycyclic aromatic hydrocarbonRelated: Coal tar is a historical source of many PAHs and a mixture used in their early study.

• AnilineNarrower topic: Early aniline production relied on aromatic compounds isolated from coal tar.

• Friedrich EngelhornBroader topic: The coal-tar residues from gas production provided feedstock for Engelhorn’s early dye business.

• Pine tarCompared with: Coal tar is a separate source of tar, with a different chemical composition and medical history.

• ResorcinolRelated: Coal tar later became an important industrial source of resorcinol.

• BenzidineRelated: Benzidine emerged from the coal-tar chemical industry that supplied early synthetic dyes.
