6-Hydroxychroman-2-carboxylic acids (I) have been found to be effective antioxidants in animal fats, vegetable oils, and emulsion systems. Two new syntheses of these compounds have been developed. Structure-activity correlations for I with various substitutents at C, C, C, and C in various test systems have been obtained. In addition, the homologous chroman acetic acids, which are also antioxidants, and a number of other derived compounds have been synthesized. The most effective antioxidant in this series is the tetramethyl compound I (R=R=R=R=CH). This compound has activity which compares well with the better commercial antioxidants.
