Spiropyrans

Spiropyrans are organic molecules known for their unique photochromatic properties, which allow them to change color upon exposure to light. These compounds are widely used in the medical and pharmaceutical fields, as well as in the development of smart materials and sensors. Spiropyrans are valuable in research related to molecular switches, optical data storage, and photoresponsive materials. At CymitQuimica, we provide a comprehensive range of high-quality spiropyrans to support your innovative research and industrial projects.
