Reducing DCM Use
As the demand for greener, more sustainable drug discovery grows, minimising the use of environmentally harmful solvents such as dichloromethane (DCM) is a key focus for synthetic chemistry teams. In this poster, Sygnature Discovery shares its internal sustainability initiative to reduce DCM use during reaction work-up – without compromising scientific integrity or product quality.
Why Reduce DCM Use?
Dichloromethane (DCM) is a popular solvent choice in synthetic chemistry, particularly for chromatography. It has high eluting power for polar compounds, volatility and availability have made it a staple in many labs.
However, DCM poses significant health and environmental risks:
- It has acute and chronic toxicity in humans, including respiratory, cardiovascular and central nervous system effects
- DCM is a suspected carcinogen and genotoxin 1
- Environmentally, DCM is persistent ((t1/2 = 18 months in water) and contributes to ozone depletion and other ecological harm 1
Sygnature’s Sustainable Chemistry Approach
In response, Sygnature Discovery has taken pre-emptive action to reduce our reliance on DCM as part of our company-wide commitment to sustainability.
Over the last five years, we’ve reduced our DCM use by over 50% – amounting to 19 tonnes of solvent – while maintaining scientific productivity and delivering on-spec products for our clients.
