Hazardous chemistry

Axplora specific expertise in energetic reactions

Hazardous chemistry, involving the use of highly energetic reactions and/or hazardous reagents, is a key technology in the process development and manufacturing toolbox of APIs, with potential to shortcut complex routes of synthesis. It enables to improve process cycle time, purity, and yield, reducing both operational costs and environmental impact.

Benefitting from decades of expertise and a strong safety culture, Axplora is a world leader in Hazardous chemistry.
