  • Applications

    Apigeninidin (CAS 1151-98-0) is a 3-deoxyanthocyanidin pigment derived from apigenin. In industrial contexts, it is used as a natural colorant in foods and cosmetics/personal care; as a dye for textiles and inks; investigated as a color-stabilizing additive for polymer/plastic formulations; and commonly evaluated as an intermediate in the synthesis of other flavonoid pigments.
