Safety of Ethyl 3-oxopentanoateIn 2022 ,《Multicomponent click polymerization for the synthesis of coumarin containing 1,4-polytriazoles and their application as dye adsorbent》 appeared in Polymer. The author of the article were Bhaumick, Prabhas; Choudhury, Lokman H.. The article conveys some information:

The synthesis of heterocycle-based polymers have remained an important area of research in polymer chem. Herein we report a one-pot synthesis of a set of novel coumarin containing regioselective 1,4-polytriazols by multicomponent click polymerization using Cs2CO3 as a base and copper(I) acetate as a catalyst in DMF medium. In this one-pot process, O-alkylation followed by a three-component click reaction between the coumarin-linked dialkyne, sodium azide and alkyl/benzyl dibromides provide novel polymers having coumarin-triazole-linker (C-T-L) units. Ten novel polymers have been synthesized with high mol. weights (Mw = 20,080-46,340 g/mol) and very good yields (83-93%). All the polymers were well characterized by IR, NMR, and GPC. The dye removal capacities of these polymers were evaluated for methylene blue (MB), rhodamine B (RB), methyl orange (MO), and congo red (CR). Polymers P1, P2, and P3 showed very high affinity towards methylene blue dye and among them, P2 showed the highest dye removal efficiency (971 mg/g) for MB. The reusability of P2 was checked and found excellent removal efficiency (RE = 96%) up to the eighth cycle. In the experiment, the researchers used many compounds, for example, Ethyl 3-oxopentanoate(cas: 4949-44-4Safety of Ethyl 3-oxopentanoate)

An efficient dual-protein (lipase and Hb) system was successfully constructed for the regioselective synthesis of quinoxalines in water. A set of quinoxalines were obtained in high yields under optimal reaction conditions. This dual-protein method exhibited a regioselectivity higher than those of previously reported methods. This study not only provided a green and mild strategy for the synthesis of quinoxalines but also expands the application of lipase and Hb in organic synthesis. The results came from multiple reactions, including the reaction of Ethyl 3-oxopentanoate(cas: 4949-44-4Related Products of 4949-44-4)

《A multifunctional fluorescent probe for highly selective detection of hydrazine and discovering the interplay between AIE and ICT》 was written by Zhu, Ji-hua; Zhang, Hao; Liao, Yuan; Liu, Jing-jiang; Quan, Zheng-jun; Wang, Xi-cun. Computed Properties of C7H12O3 And the article was included in Dyes and Pigments in 2020. The article conveys some information:

A multifunctional luminescent material (BC-B)(I) was synthesized, which exhibits aggregation-induced emission (AIE) enhancement property in high water fraction. The AIE shows a significant impact on the intramol. charge transfer (ICT) process by controlling intramol. motion. The above result is demonstrated by d. functional theory (DFT) calculations and single-crystal X-ray diffraction. To decrease the influence of AIE on ICT, the probe BC-B is exploited as turn-on fluorescent probe for hydrazine (N2H4) in DMSO/PBS buffer (6/4, volume/volume) and displays high sensitivity and selectivity. Besides, the fluorescence emission shows a good linear response (R2 = 0.9960) in the range of 0-35μM with the low detection limit of 1.29 ppb, which is significantly below the acceptable limit for hydrazine (10 ppb) set by the USEPA.
