Butyl chloride is an alkyl halide. It is used as a butylating agent in organic synthesis, e.g., in the manufacture of butyl cellulose. n-Butyl chloride is a veterinary antiparasitic (anthelmintic) drug. It is used for the removal of ascarids and hookworms from dogs and cats. n-Butyl chloride is marketed under tradenames NBC Kaps Wormer for dogs, Happy Jack Worm for dogs; Sergeants Sure Shot Capsules for cats and dogs.

Pyridine is a basic heterocyclic organic compound used as a solvent in organic synthesis. Since the pyridine ring has three double bonds, six p-electrons exist, which are sufficient for aromatic ring formation without involving the lone pair electrons of the nitrogen atom. Since the lone pair electrons remain free, quaternary salts retain the aromaticity. However, the nitrogen atom has a higher electronegativity than the carbon atoms and shows an electron-withdrawing effect. In oxidation and reduction reactions, the pyridine ring exhibits properties characteristic of pelectron-deficient aromatic rings: resistance to oxidation and facile reduction. Pyridine bases are a constituent of tars. They were isolated from coal tar or coal gas before synthetic manufacturing processes became established. Pyridine is an excellent solvent, especially for dehydrochlorination reactions and extraction of antibiotics. Large amounts of pyridine are used as starting material for pharmaceuticals and agrochemicals: for example, herbicides such as diquat and paraquat, insecticides such as chlorpyrifos, and fungicides such as pyrithione. Pyridine is harmful if inhaled, swallowed or absorbed through the skin. Effects of acute pyridine intoxication include dizziness, headache, lack of coordination, nausea, salivation, and loss of appetite.

Heptane (or n-heptane) is used in laboratories as a non-polar solvent. Recently published article describes the biological monitoring of the n-heptane exposure by its metabolite concentrations and the time course of metabolite excretion.
