In the last decade, we have started to spatially resolve the small gas and dust condensations in high-mass star-forming regions that will eventually become a massive star or system, finally being able to describe how those regions fragment.
Recent works, for example Palau et al. 2013, show that there is no correlation between the fragmentation of a region and its physical properties. But what about its chemistry?
According to Fontani et al. 2011, an interesting chemical property to investigate is the deuteration fraction, since it can be used as a chemical clock. In this contribution we show the fragmentation properties and deuteration factors obtained for a group of massive star-forming regions with SMA, PdBI, and IRAM-30m observations, and discuss what the relationship between them tells us.
