Popis:	The treatment of an aqueous solution of glycine with hypochlorite yields formaldehyde and glyoxylic acid. After acidification and removing formaldehyde by boiling glyoxylic acid reacts with resorcinol to the lactone of bis-2,4-dihydroxyphenyl acetic acid. Under alkaline conditions the lactone is oxidized to the violet oxonol anion and subsequently, after hydrolysis of the lactone, to the yellow fluorescent carboxylate anion.
