Quality Control of 4′-Hydroxyacetophenone. I found the field of Oceanography very interesting. Saw the article Carbon isotopes and lignin phenols for tracing the floods during the past 70 years in the middle reach of the Changjiang River published in 2020.0, Reprint Addresses Wu, Y (corresponding author), East China Normal Univ, State Key Lab Estuarine & Coastal Res, Shanghai 210012, Peoples R China.. The CAS is 99-93-4. Through research, I have a further understanding and discovery of 4′-Hydroxyacetophenone.
The Lake Tian E Zhou (TEZ, an oxbow lake) was formed during the rerouting of the Changjiang River in 1972, with strong influences from the main river channel and flood events. Herein, a sediment core was collected from the Lake TEZ for the measurements of carbon isotopes and biomarkers, including stable carbon isotopes (delta C-13), radiocarbon composition (Delta C-14), and lignin phenols, as well as lead-210 to reconstruct recent heavy flood events over the past 70 years. At the 24-26 cm interval, the sediment contained the highest OC%, TN%, and lignin phenols content, as well as significantly depleted C-13 but enriched C-14, corresponding to the extreme flood event in 1998. In addition, statistics from t-test showed that lignin phenols normalized to OC (?8), the concentration of 3, 5-dihydroxy benzoic acid (3, 5-BD), and the ratio of p-hydroxy benzophenone to total hydroxyl phenols (PHB/HP) were all significantly different between the layers containing flood deposits and the layers deposited under normal non-flood conditions (p<0.05). These results indicate that the later three parameters are highly related to flood events and can be used as compelling proxies, along with sediment chronology, for hydrological changes and storm/flood events in the river basin and coastal marine environments.
