  • Applications

    Mercury(II) sulfide (CAS 1344-48-5) is primarily used as a red pigment (vermilion) in coatings and inks and as a colorant in plastics and other polymers; it also serves as a pigment in ceramics and glazes, and historically has been employed in art and decorative paints. Because it contains mercury, its use is subject to regulatory restrictions and formulation limits depending on regional rules.
