title: Determination of degree of substitution of formyl groups in polyaldehyde dextran by the hydroxylamine hydrochloride method.
abstract: Colorimetric or potentiometric titration of the aldehyde residues in polyaldehyde dextran by the hydroxylamine hydrochloride/sodium hydroxide method has been found to be a convenient and accurate method to determine formyl content. Nitrogen combustion analyses on the isolated oximes confirmed the titrametric results.
