Crystal clear and colorful

Crystal structure of Phenyl-2-hydroxybenzoate or phenyl salicylate, or salol, is presented here by using polarization microscopy. It is a chemical substance, introduced in 1886 by Marceli Nencki of Basel. It can be created by heating salicylic acid with phenol. It appears in the form of small white crystals or crystalline powder with pleasant aromatic odour and taste.

Once used in sunscreens, phenyl salicylate is now used in the manufacture of some polymers, lacquers, adhesives, waxes and polishes. It has been used as an antiseptic based on the antibacterial activity upon hydrolysis in the small intestine. It acts as a mild analgesic.
