Photochromic Dyes

Photochromic dyes change color when exposed to light, particularly UV light, and are widely used in applications such as smart coatings, lenses, and optical data storage. These dyes are also essential for molecular and materials science research involving light-sensitive compounds. At CymitQuimica, we provide a variety of high-quality photochromic dyes for advanced research and commercial applications.
