Indigo carmine (860-22-0)
indigo · Indigo Blue · indigotin
Indigo carmine, or 5,5′-indigodisulfonic acid sodium salt, is an organic salt derived from indigo by sulfonation, which renders the compound soluble in water. It is approved for use as a food colorant in the U.S and E.U., It has the E number E132. It is also a pH indicator.
Benzaldehyde (C6H5CHO) is an organic compound consisting of a benzene ring with a formyl substituent. It is the simplest aromatic aldehyde and one of the most industrially useful. It is a colorless liquid with a characteristic almond-like odor.
Acetophenone is the organic compound with the formula C6H5C(O)CH3 (also represented by the pseudoelement symbols PhAc or BzMe). It is the simplest aromatic ketone. This colorless, viscous liquid is a precursor to useful resins and fragrances.
octenol · 1-octen-3-ol, (+-)-isomer · 1-octen-3-ol, (R)-isomer
1-Octen-3-ol, octenol for short and also known as mushroom alcohol, is a chemical that attracts biting insects such as mosquitoes. It is contained in human breath and sweat, and it was once believed that insect repellent DEET works by blocking the insects' octenol odorant receptors. 1-Octen-3-ol is a secondary alcohol derived from 1-octene.
BENZOPHENONE (119-61-9, 84-65-1)
Benzophenone is the organic compound with the formula (C6H5)2CO, generally abbreviated Ph2CO. Benzophenone is a widely used building block in organic chemistry, being the parent diarylketone.
2-Acetyl-5-methylfuran is an organic compound with the chemical formula C 7H 8O 2.
Furan is a heterocyclic organic compound, consisting of a five-membered aromatic ring with four carbon atoms and one oxygen. Chemical compounds containing such rings are also referred to as furans. Furan is a colorless, flammable, highly volatile liquid with a boiling point close to room temperature.
Safrol · 4 Allyl 1,2 methylenedioxybenzene · 4-Allyl-1,2-methylenedioxybenzenes
Safrole is a phenylpropene. It is a colorless or slightly yellow oily liquid typically extracted from the root-bark or the fruit of sassafras plants in the form of sassafras oil (although commercially available culinary sassafras oil is usually devoid of safrole due to a rule passed by the FDA in 1960), or is synthesized from catechol or other related methylenedioxy compounds. It is the principal component of brown camphor oil, and is found in small amounts in a wide variety of plants, where it functions as a natural pesticide.
Isodecanol (25339-17-7, 68551-08-6, 68526-85-2)
m-hydroxybenzaldehyde · meta-hydroxybenzaldehyde
3-Hydroxybenzaldehyde is one of the three isomers of hydroxybenzaldehyde.
methyl nonyl ketone · BioUD · undecan-2-one
2-Undecanone, also known as methyl nonyl ketone and IBI-246, is an oily organic liquid manufactured synthetically, but which can also be extracted from oil of rue. It is found naturally in bananas, cloves, ginger, guava, strawberries, wild-grown tomatoes, and the perennial Houttuynia cordata.
