Carboxymethyl pachyman gives a red color when treated with phenol and concentrated sulfuric acid. The reaction is sensitive and the color is stable. Based on this reaction, a colorimetric method has been developed to analyse carboxymethyl pachyman, and some factors that affect the determination were discussed.
