Benzoic acid is a white crystalline solid organic compound with the chemical formula C6H5COOH. The name “benzoic acid” is derived from gum benzoin, a resinous substance obtained from the styrax plant indigenous to South Asia.
Acetone, also known as 2-propanone, is a colorless, flammable liquid with a pungent odor and low viscosity. It is the simplest ketone, with the formula C3H6O. Acetone is miscible with water, meaning it mixes readily with water in any proportion.
Oxalic acid is the simplest saturated dicarboxylic acid with the formula C2H2O4. It is a white solid that occurs naturally in the form of a dihydrate. Anhydrous compound must be produced from the dihydrate even when manufactured industrially.
Phenol, also known as hydroxybenzene, is an organic compound with the chemical formula C6H5OH. It is a white crystalline solid at room temperature, but technical grade phenol can be a liquid due to impurities. It has a distinct odor, often described as sickeningly sweet and tarry.
Vitamin B3 is one of the vitamins of the B complex. It is also called niacin. The terms niacin or vitamin B3 are generally used as generic descriptors for both nicotinic acid and nicotinamide.
Phloroglucinol, also known as 1,3,5-trihydroxybenzene, is an organic compound with the chemical formula C6H6O3. It is colorless to beige solid at room temperature and is soluble in water, ethanol, and diethyl ether.
Pyrogallol, also known as 1,2,3-trihydroxybenzene, is a white crystalline solid with the formula C6H6O3. Pyrogallol exists in the form of colorless needles or leaflets, which gradually change color to dark gray upon exposure to air or light.
1,3-Propanediol is a clear, colorless, odorless liquid that is miscible with water, alcohols, ethers, and formamide. It is sparingly soluble in benzene and chloroform.
Butanone also known as methyl ethyl ketone, MEK, is an aliphatic ketone and, next to acetone, the most important commercially produced ketone. It is a is a colorless, low-viscosity, flammable liquid with a characteristic ketone-like odor similar to that of acetone.
4-Methyl-2-pentanone is a colorless liquid with a less pronounced ketone-like odor.
3-Methyl-2-butanone is a colorless liquid with a characteristic ketone odor.
Hydroquinone, also known as 1,4-benzenediol, is a colorless crystalline solid when pure, with the chemical formula C6H4(OH)2. It is an aromatic diol (a para-isomer of catechol).
