Isopropyl alcohol, also known as isopropanol or 2-propanol, is the simplest secondary alcohol with the chemical formula C3H7OH. It is a colorless, volatile, and flammable liquid that has a a slightly bitter taste and a faint odor similar to a mixture of ethanol and acetone.
Titanium dioxide is an inorganic compound with the chemical formula TiO2. It's a white solid that is insoluble in water. Titanium dioxide is found naturally as rutile, anatase, and brookite polymorphs.
Commercial titanium dioxide is manufactured via two distinct industrial methods: the sulfate process and the chloride process.
The raw materials for titanium dioxide production include natural products such as ilmenite, leucoxene, and rutile, and some very important synthetic materials such as titanium slag and synthetic rutile.
Zinc oxide is an inorganic compound with the chemical formula ZnO. It's a white powder that is insoluble in water. While it can occur naturally as the mineral zincite, most zinc oxide used commercially is produced synthetically.
o-Cresol, also known as 2-methylphenol, is an organic compound with the chemical formula C7H8O. It is a colorless crystalline solid at room temperature with a phenolic odor that is highly soluble in most organic solvents.
Cresols are primarily produced by different processes such as alkali fusion of toluenesulfonates, alkaline chlorotoluene hydrolysis, splitting of cymene hydroperoxide, and vapor-phase methylation of phenol.
Coumarin poses significant health risks. Ingestion, inhalation, and eye contact are hazardous, while skin contact is less severe. Acute overexposure can be fatal. Coumarin shows moderate toxicity to liver and kidneys, with a median lethal dose of 275 mg/kg. Hepatotoxicity is more pronounced in rats than mice.
The molar mass of a chemical compound is a fundamental concept in chemistry, representing the mass of one mole of that substance. Expressed in grams per mole (g/mol), it's essentially the weight of 6.022 x 1023 (Avogadro's number) particles of the compound. Understanding molar mass is crucial for various chemical calculations, from determining reactant quantities in a reaction to preparing solutions of a specific concentration.
Indole, also known as 1-benzo[b]pyrrole, is an aromatic heterocyclic organic compound that has a bicyclic structure (a benzene fused to a pyrrole) with the chemical formula C8H7N. It is a colorless solid with a very persistent musty odor.
Coumarin, also known as 2H-1-benzopyran-2-one or 1,2-benzopyrone, is a natural aromatic lactone with the chemical formula C9H6O2. It is a colorless crystalline solid with a bittersweet odor like hay and is used as a fixative in perfumes.
Cyclohexanone is an organic compound with the chemical formula C6H10O. It is a colorless to pale yellow liquid with an odor similar to that of acetone that is very soluble in most organic solvents.
