| Popis: | 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‐sulpho‐phenylazo)‐2‐naphthalenesulphonic acid, which is an azo‐coupling product between the meta‐isomer of cresidine‐p‐sulphonic acid (CSA) and Schaeffer's salt (SS). |
