title: Photometric determination of alpha-ketoglutaric acid with diazotized sulphanilic acid.
abstract: A new photometric method for the determination of alpha-ketoglutaric acid is presented. It is based on the colour reaction of alpha-ketoglutaric acid in sodium hydroxide solution with diazotized sulphanilic acid in the presence of sodium sulphite and sodium hypophosphite. This method is highly sensitive and fairly selective for alpha-ketoglutaric acid, and may be suitable for the determination of the acid in complex samples.
