Toluene is a colorless, water-insoluble liquid with the smell associated with paint thinners. It is a mono-substituted benzene derivative, consisting of a CH3 group attached to a phenyl group. The major use of toluene is as a mixture added to gasoline to improve octane ratings. Toluene is also usedto produce benzene and as a solvent in paints, coatings, synthetic fragrances, adhesives, inks, and cleaningagents. Toluene is also used in the production of polymers used to make nylon, plastic soda bottles, andpolyurethanes and for pharmaceuticals, dyes, cosmetic nail products, and the synthesis of organicchemicals. The CNS is the primary target organ for toluene toxicity in both humans and animals for acute and chronicexposures. CNS dysfunction (which is often reversible) and narcosis have been frequently observed inhumans acutely exposed to low or moderate levels of toluene by inhalation; symptoms include fatigue,sleepiness, headaches, and nausea. CNS depression and death have occurred at higher levels of exposure. Toluene is used in veterinary medicine as a treatment for various parasites in dogs and cats. It is used for the removal of ascarids (Toxocara canis and Toxascaris leonina) and hookworms (Ancylostoma caninum and Uncinaria stenocephala) and as an aid in removing tapeworms (Taenia pisiformis, Dipylidium caninum, and Echinococcus granulosus) from dogs and cats.

Methyl ethyl ketone (butanone) is an industrial solvent produced on a large scale. It is used in surface coatings, adhesives, printing inks, chemical intermediates, magnetic tapes, and lube oil dewaxing agents. Methyl ethyl ketone has a fruity odor similar to acetone. It is used as a flavor/fragrance agent in pharmaceuticals and cosmetics.

Stannous 2-ethylhexanoate is the stannous salt of 2-ehylhexanoic acid. It is used in the chemical industry as a catalyst for ring-opening polymerization of cyclic diesters in the production of polylactic acid and in the production of urethane foams, silicon, and other polymers.

Benzyl chloride, or α-chlorotoluene, is a reactive organochlorine compound that is a widely used chemical building block. Industrially, benzyl chloride is the precursor to benzyl esters which are used as plasticizers, flavorants, and perfumes. Phenylacetic acid, a precursor to pharmaceuticals, is produced from benzyl cyanide, which is generated by treatment of benzyl chloride with sodium cyanide. Quaternary ammonium salts, used as surfactants, are readily formed by alkylation of tertiary amines with benzyl chloride. Benzyl chloride is an alkylating agent with very irritating properties to the skin. Indicative of its high reactivity (relative to alkyl chlorides), benzyl chloride reacts with water in a hydrolysis reaction to form benzyl alcohol and hydrochloric acid. In contact with mucous membranes, hydrolysis produces hydrochloric acid. Thus, benzyl chloride is a lachrymator and has been used in chemical warfare.

Trimegestone is a 19-norpregnane progestin. It has a potent progesterone receptor and very low androgen receptor affinities but no detectable affinity to oestrogen receptor. Trimegestone has been developed for use in conjunction with oestrogen and 17-beta-estradiol for postmenopausal hormone replacement therapy. In vitro studies have shown that trimegestone can inhibit cytochrome P450 2C19 (CYP2C19). Although its clinical importance is unknown, trimegestone can moderately elevate the plasma concentration of drugs metabolized through CYP2C19, such as citalopram, imipramine and diazepam. Trimegestone is an effective and well-tolerated new progestin, which does not negate the beneficial effects of oestrogen on lipids.

Cobaltous carbonate is used as a feed additive for ruminants, horses and rabbits (dietary cobalt is needed for vitamin B12 synthesis). Cobaltous carbonate has carcinogen, mutagen and reproduction toxicant properties. Cobaltous carbonate is a skin and eye irritant, and a dermal and respiratory sensitizer. Its dust is a hazard to persons handling the substance. Exposure by inhalation must be avoided.

Sodium anthranilate is an excipient (pharmacologically inactive substance). Sodium anthranilate (Aminobenzoate sodium ,C7H6NNaO2), also known as sodium 2-aminobenzoate, is an organic amine. Aminobenzoate sodium exists as a yellow powder for use in pharmaceutical processing.

Lead chromate (previously known as chrome yellow), an insoluble chromium metal salt that widely used as a pigment in the production of paints, coatings, and plastics. Lead chromate possessed tumorigenic, genotoxic and clastogenic properties and was substituted by another pigment, cadmium yellow.
