摘要
A major subsidiary dye in US certified Allura Red AC dye (FD&C Red No. 40) has been isolated by preparative high performance liquid chromatography. The paper chromatographic properties of the isolated dye indicate that it is the dye designated as SC-NTR in a previous paper (Marmion 1971). Spectroscopic analysis of the isolated dye is consistent with the disodium salt of 6-hydroxy-5-(2-methoxy-5-methyl-3-sulphophenylazo)-2-naphthalenesulphonic acid, which is an azo-coupling product between the meta-isomer of cresidine-p-sulphonic acid (CSA) and Schaeffer's salt (SS).
