  • Applications

    6-Hydroxycyanidin (CAS 42529-06-6) is an anthocyanidin pigment that is considered primarily as a natural colorant and dye precursor. In cosmetics and personal care, it can be used as a colorant to impart red-to-purple hues in formulations, subject to stability considerations and regulatory constraints. In food processing and beverages, it may be evaluated as a natural colorant under appropriate regulatory approvals, with attention to pH- and heat-related stability. In coatings, inks, and polymeric materials, it can serve as a pigment or dye intermediate for coloration of paints, printed inks, and colored plastics. In industrial manufacturing, it is used as an intermediate in dye synthesis and pigment development, and in analytical settings it may act as a reference pigment for spectroscopic studies. All usage is subject to local regulations and formulation limits.
