Individually, or as an integrated chemical workstation, these tools provide critical support for better synthesis reactions:


EasySampler is an automated, unattended giải pháp công nghệ delivering representative and reproducible samples. The probe-based công nghệ has a micro-pocket, which takes samples at any given time, quenches in-situ and dilutes for ready to analyze offline samples. 

EasySampler supports reaction understanding by providing samples on demvà. Sampling is performed under reaction conditions, making it truly representative. The samples, once collected & time stamped, can be analyzed via offline analytical methods and the result integrated baông xã inkhổng lồ the data stream. An additional value lies in the increased data quality through automatic và seamless data collection. The increased accuracy và precision of automated sampling provides higher quality versus manual sampling.

Featured Article: Understanding α,β-Unsaturated Imine Formation

Determine Relative Reaction Rates và Further Mechanistic Understanding

Calow, A. D. J., Carbó, J. J., Cid, J., Fernández, E., và Whiting, A. (2014). Understanding α,β-Unsaturated Imine Formation from Amine Additions lớn α,β-Unsaturated Aldehydes and Ketones: An Analytical and Theoretical Investigation.The Journal of Organic Chemistry,79(11), 5163–5172. In previous work, the researchers had reported a catalytic method lớn synthekích cỡ chiral γ-amino alcohols via in situ generation of α,β-unsaturated imines. They stated that there was a lack of kinetic or mechanistic studies regarding the relative 1,2- versus 1,4- addition of primary amines to lớn α,β-unsaturated aldehydes & ketones. To further this understanding, the researchers used in situ ReactIR spectroscopy along with NMR studies & DFT calculations, khổng lồ better characterize the addition of primary amines lớn α,β-unsaturated aldehydes and ketones (1,2- vs 1,4-addition) và examine the relative rates of these reactions.
