Characterizing agrochemical degradation products of BoostCrop
Researchers at HFML-FELIX have used the FELIX laser to elucidate the structure of the solar-induced degradation products of Sinapoyl Malata, one of the photomolecular heater agrochemicals developed by the BoostCrop consortium. The agrochemical photomolecular heaters aim to stimulate plant growth by heating the plant's microclimate to create more favourable growth conditions by converting parts of the solar spectrum not used for photosynthesis to heat.
This work has now been published in the ACS Agricultural Science & Technology journal with the title Characterization of Solar Radiation-Induced Degradation Products of the Plant Sunscreen Sinapoyl Malate.
Considering human safety
In the development of new agrochemical products, an aspect to consider is their environment and human safety, not only for the newly developed compound but also for its degradation products generated during its application. For these studies, a confident assignment of the chemical structure of the generated byproducts is required, which is not always possible with conventional LC-MS approaches.
Here, we have demonstrated that the identification of UV-photodegradation products can be made reference-free using the combination of LC-MS/MS, IRIS, and DFT using minimal sample volumes of only 6 μL. This sensitivity may aid in the identification process of transformation products in cases where conventional elucidation is impossible/infeasible due to low concentrations and/or complex sample matrices.
