Anisole, or methoxybenzene, is an organic compound with the formula . It is a colorless liquid with a smell reminiscent of anise seed, and in fact many of its derivatives are found in natural and artificial fragrances. The compound is mainly made synthetically and is a precursor to other synthetic compounds. Structurally, it is an ether () with a methyl () and phenyl () group attached. Anisole is a standard reagent of both practical and pedagogical value.

Dehydroepiandrosterone (DHEA), also known as androstenolone, is an endogenous steroid hormone precursor. It is one of the most abundant circulating steroids in humans. DHEA is produced in the adrenal glands, the gonads, and the brain. It functions as a metabolic intermediate in the biosynthesis of the androgen and estrogen sex steroids both in the gonads and in various other tissues. However, DHEA also has a variety of potential biological effects in its own right, binding to an array of nuclear and cell surface receptors, and acting as a neurosteroid and modulator of neurotrophic factor recep

Nepetalactones are a group of iridoid analog stereoisomers produced by Nepeta cataria (catnip) and certain other plants in the genus Nepeta in order to repel insects. They are also produced by many aphids, in which they are sex pheromones. Nepetalactones are cat attractants, and cause the behavioral effects that catnip induces in domestic cats. However, they affect visibly only about two thirds of adult cats. They produce similar behavioral effects in many other felids, especially in lions and jaguars. In 1941, the research group of Samuel M. McElvain was the first to determine the structures

Myrcenol is an organic compound, specifically a terpenoid. It is most notable as one of the fragrant components of lavender oil.

3-Mercapto-3-methylbutan-1-ol, also known as MMB, is a common odorant found in food and cat urine. The aromas ascribed to MMB include catty, roasty, broth-like, meaty, and savory, or similar to cooked leeks.

Ectocarpene is the rearrangement product of pre-ectocarpene, the sexual attractant, or pheromone, found with several species of brown algae (Phaeophyceae). Ectocarpene has a fruity scent and can be sensed by humans when millions of algae gametes swarm the seawater and the females start emitting the substance's precursor to attract the male gametes.

Lineatin is a pheromone produced by female striped ambrosia beetle, Trypodendron lineatum Olivier. These kinds of beetles are responsible for extensive damage of coniferous forest infestation in Europe and North America. Since lineatin can act as lures used for mass-trapping of T. lineatum, it is being studied to apply as a pest control reagent.

Verbenol (2-pine-4-ol) is a group of stereoisomeric bicyclic monoterpene alcohols. These compounds have been found to be active components of insect pheromones and essential oils. ==Isomers==

4-Vinylanisole is an organic compound with the formula CH3OC6H4CH=CH2. It is one of three isomers of vinylanisole. A colorless liquid, 4-vinylanisole is found in a number of foods and drinks. It is also a monomer for the synthesis of modified polystyrenes. It is an aggregation pheromone used by locusts.
