Indole is an aromatic heterocyclic organic compound. It has a bicyclic structure, consisting of a six-membered benzene ring fused to a five-membered nitrogen-containing pyrrole ring. Indole is a popular component of fragrances and the precursor to many pharmaceuticals.

Benzothiazole is an organosulfur compound. It is colourless, slightly viscous liquid. A derivative of benzothiazole is the light-emitting component of luciferin, found in fireflies.

Benzotriazole is a heterocyclic compound. It is commonly used as a corrosion inhibitor. It is a colourless solid that is soluble in polar solvents, including water. Benzotriazoles are also a class of compounds containing the benzotriazole skeleton.

Tetracene has the appearance of a pale orange powder. Tetracene is the four-ringed member of the series of acenes.It is a molecular organic semiconductor, used in organic field-effect transistors (OFETs) and organic light-emitting diodes (OLEDs).

Cocamidopropyl betaine is a synthetic surfactant derived from coconut oil and dimethylaminopropylamine.

Biotin is a water-soluble B-complex vitamin (vitamin B7).  It was discovered by Bateman in 1916. It is composed of a ureido (tetrahydroimidizalone) ring fused with a tetrahydrothiophene ring.

Aspidophytine is an indole alkaloid that has attracted a lot of attention from synthetic chemists. An extract of the cockroach plant, aspidophytine is an insecticidal substance particularly effective against cockroaches.

Butyrophenone is a chemical compound, some of its derivatives (called commonly butyrophenones) are used to treat various psychiatric disorders such as schizophrenia, as well as acting as antiemetics.

Benperidol is a butyrophenone derivative. It is an antipsychotic which can be used for the treatment of schizophrenia, but it is primarily used to control antisocial hypersexual behaviour, and is sometimes prescribed to sex offenders as a condition of their parole, as an alternative to anti-androgen drugs such as cyproterone.

Anthracene is a solid polycyclic aromatic hydrocarbon consisting of three fused benzene rings. It is a component of coal-tar. Anthracene is used in the production of the red dye alizarin and other dyes.

Benzoyl chloride is an organochlorine compound with the formula C₆H₅COCl. It is a colourless, fuming liquid with an irritating odour. It is mainly useful for the production of peroxides but is generally useful in other areas such as in the production of dyes, perfumes, pharmaceuticals, and resins.

Cadaverine is a foul-smelling compound produced by protein hydrolysis during putrefaction of animal tissue. Cadaverine is a toxic diamine with the formula NH₂(CH₂)₅NH₂, which is similar to putrescine.

Caffeine is found in varying quantities in the seeds, leaves, and fruits of some plants, where it acts as a natural pesticide that paralyzes and kills certain insects feeding on the plants. It is most commonly consumed by humans in infusions extracted from the bean of the coffee plant and the leaves of the tea bush.

Acetylene is a hydrocarbon and the simplest alkyne. This colourless gas is widely used as a fuel and a chemical building block. It is unstable in pure form and thus is usually handled as a solution.

Benzil is the organic compound with the formula (C₆H₅CO)₂, generally abbreviated (PhCO)₂. This yellow solid is one of the most common diketones. Its main use is as a photoinitiator in polymer chemistry.

Buspirone is a psychoactive drug and pharmaceutical medication of the piperazine and azapirone chemical classes. It is used primarily as an anxiolytic, specifically for generalized anxiety disorder.

Bromophenol blue ,3',3,5',5-tetrabromophenolsulfonphthalein is used as an acid-base indicator, a colour marker and a dye.

Captopril is an angiotensin-converting enzyme inhibitor (ACE inhibitor) used for the treatment of hypertension and some types of congestive heart failure.

Acetic acid is an organic compound with the chemical formula CH₃COOH. It is a colourless liquid that when undiluted is also called glacial acetic acid. As the main component of vinegar, it has a distinctive sour taste and pungent smell.

Aspartic acid is an α-amino acid with the chemical formula HOOCCH(NH₂)CH₂COOH. The carboxylate anion, salt, or ester of aspartic acid is known as aspartate. The L-isomer of aspartate is one of the 20 proteinogenic amino acids, i.e., the building blocks of proteins. Its codons are GAU and GAC.

2-Bromo-1-chloropropane, C₃H₆BrCl, is an alkyl halide. This simple compound has a chiral centre and is used sometimes to determine the enantiomeric resolution of simple chromatographic methods.

Butene is an alkene with the formula C₄H₈. It is a colourless gas that is present in crude oil as a minor constituent in quantities that are too, small for viable extraction. It is ,therefore, obtained by catalytic cracking of long chain hydrocarbons left during refining of crude oil.

2,2'-Bipyridine is an organic compound with the formula (C₁₀H₈N₂). It is an important isomer of the bipyridine family. It is a bidentate chelating ligand, forming complexes with many transition metals.

Bromacil is an organic compound with the chemical formula C₉H₁₃BrN₂O₂, commercially available as a herbicide.

Caprolactam is an organic compound with the formula (CH₂)₅C(O)NH. This colourless solid is a lactam or a cyclic amide of caproic acid. Caprolactam is the precursor to Nylon 6, a widely used synthetic polymer.
