Acts as a Lewis acid catalyst in various organic synthesis reactions, including glycosylation and Friedel-Crafts acylations.

Used in the synthesis of bismuth-containing nanomaterials for catalytic and optoelectronic applications.

Employed in analytical chemistry as a reagent for detecting the presence of certain anions, such as phosphate and sulfide.

Serves as a precursor in the preparation of other bismuth compounds used in pharmaceuticals (e.g., bismuth subsalicylate for gastrointestinal treatments) and cosmetics (e.g., bismuth oxychloride for pearlescent effects).

Applied in some antiseptic and astringent formulations due to its mild antimicrobial properties against certain bacteria.

Utilized in the electronics industry for producing bismuth-based semiconductors and thermoelectric materials.

In the metal industry, used in processes for bismuth recovery and preparation of low-melting alloys for fuses and electrical components.
