Used as a dye intermediate in textile and printing industries due to its azo group structure, providing bright yellow to orange shades. Also applied in research for developing new photochromic materials because of its light-sensitive azo and thiopyrimidinone components. Shows potential in analytical chemistry as a colorimetric reagent for metal ion detection (particularly copper and iron) and pH changes, forming stable colored complexes responsive to environmental conditions. Investigated as a starting material or intermediate in synthesizing bioactive compounds for pharmaceutical research, exhibiting antimicrobial, antioxidant, and anti-inflammatory activities. Additionally, demonstrates enzyme inhibitory effects, such as on tyrosinase, with potential applications in skincare products to reduce pigmentation, freckles, or spots, though not yet commercialized.
