The utilization of ultraviolet (UV) or visible light in chemical reactions is a well-established and highly regarded approach in the field of chemistry. It is known for its green attributes, making it a cornerstone of sustainable technology and environmentally friendly practices. Recent advancements in LED (light-emitting diode) lighting technology and the development of novel photoredox catalysts have opened up new frontiers in the application of visible light, enabling a wide range of chemical reactions that were previously considered “forbidden” or challenging to achieve. Photochemistry has a number of key advantages listed below.

Sustainable Chemistry: Light as a reagent aligns with green and sustainable chemistry principles, reducing reliance on hazardous traditional reagents and minimizing hazardous reagent use.

Photoredox Catalysts: Novel photoredox catalysts enhance the scope of photochemical reactions and allow the use of visible light.

Overcoming ‘Forbidden’ Reactions: Previously impractical reactions have become accessible, bypassing high energy barriers through visible light-driven photochemistry.

Selectivity and Precision: Photochemical reactions offer high selectivity, enabling accurate control of specific chemical bonds.

At Symeres, our expertise in the realm of  photochemistry extends back for more than two decades , initially starting with UV-induced isomerization of vitamin D and its related derivatives. Over the years, we have refined and expanded our capabilities within the photochemistry arena, resulting in a comprehensive suite of service that enable us to deliver solution for our clients’ diverse chemical challenges. 

Our services within the domain of photochemistry encompass a broad spectrum of capabilities and applications, including: 

  • High-throughput library synthesis: Utilizing ,for example, [2+2] cycloadditions in a photoflow setup,  access to hundreds of novel compounds with high sp3 character can be readily achieved. A wide range of bicyclic scaffolds has been synthesized at Symeres for our Symegold library using this method.

  • Process Scale-Up: Our experience extends beyond the laboratory scale, and we are adept at scaling up photochemical processes up to kg productions. Using setups derived from readily available lights (LED and UV-C), batch-type vessels, or continuous-flow hardware we keep engineering principles in mind for the highest possible photon efficiency. We can ensure seamless transition from small-scale proof of concept to large-scale manufacturing.  

For the use of photochemistry at any stage of your drug development, Symeres is the partner of choice.
