Lactic acid, also known as 2-hydroxypropionic acid, is a natural organic acid with the molecular formula CH3CH(OH)COOH. Pure lactic acid is a white, crystalline solid with a low melting point that is found in many biological systems, including the human body.
Dioxane, or 1,4-dioxane, is a heterocyclic diether with the formula C4H8O2. It is a flammable, colorless liquid with a faint, sweet odor similar to diethyl ether. It is known by other names such as p-dioxane, diethylene oxide, diethylene dioxide, diethylene ether, 1,4-dioxacyclohexane, dioxyethylene ether, and dioxan.
Isoprene, also known as 2-methyl-1,3-butadiene, is a five-carbon hydrocarbon that exists in nature at trace levels. It is a colorless, volatile liquid with the chemical formula C5H8.
Tetrahydrofuran (THF), also known as oxolane, is a cyclic ether with the chemical formula C4H8O. It has a wide application in the chemical industry.
Crotonic acid is the trans-isomer of 2-butenoic acid. It is a short-chain, unsaturated carboxylic acid with the chemical formula CH3CH=CHCOOH. The cis isomer of 2-butenoic acid is known as isocrotonic acid.
Crotonaldehyde [4170-30-3], also known as 2-butenal, is a colorless liquid with a pungent odor and strong lacrimatory properties. It has a chemical formula of CH3CH=CHCHO, and it exists as two stereoisomers: cis-crotonaldehyde [15798-64-8] and trans-crotonaldehyde [123-73-9].
Perchloric acid is a strong mineral acid with the chemical formula HClO4. It is a colorless, odorless liquid that is usually found in aqueous solutions. Perchloric acid is one of the strongest Brønsted-Lowry acids.
Sodium chlorite is the sodium salt of the unstable chlorous acid with the formula NaClO2. It appears as a white, crystalline solid that is soluble in water.
Chlorine dioxide is an inorganic chemical compound with the formula ClO2. It exists as a yellowish-green gas at room temperature, a reddish-brown liquid between 11 °C and −59 °C, and as bright orange crystals below −59 °C. It is usually handled as an aqueous solution and is produced on-site for industrial applications.
During World War II, research on chlorinated phenoxy compounds led to the discovery of 2,4-dichlorophenoxyacetic acid (2,4-D) as a selective herbicide. This discovery revolutionized weed control in grasses and related crops like cereals, rice, and sugarcane.
Trimethylamine is an organic compound with the formula N(CH3)3. It is a colorless gas or compressed liquid with a strong fishy odor, at low concentrations. At higher concentrations, the odor becomes more ammonia-like.
Dimethylamine is an organic compound with the formula (CH₃)₂NH. It is a colorless, flammable gas with an ammonia-like odor, although at low concentrations it can smell like fish, and its odor is more potent than methylamine and less than trimethylamine. Dimethylamine is commonly encountered commercially as a solution in water at concentrations up to around 40%.
