Spectrophotometric determination of some phenols with sodium metaperiodate and aminophenols.
New spectrophotometric methods have been developed for the assay of some phenols by use of two pairs of reagents, m-aminophenol and periodate (for catechol, catecholamines, eugenol and guaiacol) and metol and periodate (for pyrogallol, gallic acid, propyl gallate, phloroglucinol and butylated hydroxyanisole). The methods are simple, sensitive, reproducible, accurate within +/- 1.0%, and applicable to the assay of antioxidants (gallic acid, propyl gallate and butylated hydroxyanisole) in oils and fats, catecholamines in dosage forms, and eugenol in clove oil.
