  • Applications

    Barium lithol red (CAS 1103-38-4) is primarily used as a colorant and as an intermediate in azo dye synthesis, with practical applications across several industries: as a colorant in coatings; as a pigment/colorant in inks and in plastics; as a dye source or precursor in textile and leather coloration; and as a pigment additive in paper coatings and packaging formulations. Use is formulation-dependent and subject to local regulations and limits.
