An alkaloid (1), an amide (2), three lactones (3, 6 and 7), two coumarins (4-5), eight lignans (8-15), four alcs. (16-19) and three phenols (20-22) are obtained from the EtOAc soluble portion of the MeOH extract of the rhizome of Menispermum dauricum DC. The chem. structures of the compounds are determined by using spectroscopic methods and further supported by comparison with previous literatures. This is the first report that compounds 4-5, 12-17, 19 and 20-21 are obtained from the family Menispermaceae. Compounds 1-2, 6-11 and 22 are isolated for the first time from Menispermum genus. The chemotaxonomic significance of the compounds is also discussed. This study involved multiple reactions and reactants, such as 4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1Recommanded Product: 2380-78-1).

4-Hydroxy-3-methoxyphenethanol (cas: 2380-78-1) belongs to ethers. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Esters are more polar than ethers but less polar than alcohols. They participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding confers some water-solubility.Recommanded Product: 2380-78-1

Phytochemical and network-based chemotaxonomic study on Thalictrum foliolosum was written by He, Gongxiu;Tu, Xichen;Yan, Yuanfeng;Peng, Jun;Yin, Tianpeng. And the article was included in Biochemical Systematics and Ecology in 2022.Reference of 2380-78-1 The following contents are mentioned in the article:

Phytochem. investigation on the whole herbs of Thalictrum foliolosum DC. (Ranunculaceae) led to the isolation of eighteen compounds, including nine isoquinoline alkaloids (1-9) and nine nonalkaloidal constituents (10-18). Among them, compounds 11-14 and 16-18 have not been previously isolated from this genus, while compounds 1, 7, 10, and 15 have not been previously found in this species. The chemotaxonomic values of these compounds were explored by compound-species network anal. Some of the isolated compounds (1, 7, 10) showed limited distribution in the genus, which could serve as chemotaxonomic markers to facilitate species identification of T. foliolosum.

And the article was included in Molbank in 2021.Safety of 2-Methoxyethylamine The following contents are mentioned in the article:

The ongoing study is a Ugi-azide four-component reaction for the synthesis of 1,5-disubstituted tetrazole (1,5-DST), which involves an aldehyde, different amines, isocyanides, and as azide source trimethylsilyl azide (TMSN₃), in water as solvent using as catalyst tetradecyltrimethylammonium bromide (TTAB) (10 mol%), which provides a hydrophobic micellar reaction site. This approach is a step toward a green chem. reaction of 1,5 disubstituted tetrazole. A series of 1,5-disubstituted tetrazoles is synthesized with a large substrate scope, leading to yields between 43% and 56%, which are compared afterwards with those obtained with methanol as solvent. This study involved multiple reactions and reactants, such as 2-Methoxyethylamine (cas: 109-85-3Safety of 2-Methoxyethylamine).

2-Methoxyethylamine (cas: 109-85-3) belongs to ethers. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Safety of 2-Methoxyethylamine

Several new interlayer-grafted derivatives of kaolinite were synthesized by esterification of inner-surface hydroxyl groups with alkanols, diols and glycol mono-ethers starting with the DMSO intercalate.

The grafted mols. are arranged in monolayers between the kaolinite layers, with typical basal spacings of ∼11.3 Å. Rheol. studies of aqueous dispersions of the modified kaolinites revealed an exponential increase of the yield value and apparent viscosity with increasing alkyl chain length of the grafted mols.

Effect of flotation frothers on bubble size and foam stability was written by Cho, Y. S.;Laskowski, J. S.. And the article was included in International Journal of Mineral Processing in 2002.Recommanded Product: 2-(2-(Hexyloxy)ethoxy)ethanol The following contents are mentioned in the article:

In order to study the effect of frothers on the size of bubbles, experiments were carried out by using single- and multi-hole spargers and a flotation cell. The size of bubbles strongly depends on frother concentration only when multi-hole spargers are utilized (or when measured in a flotation cell). At low frother concentrations (C < CCC), the bubble size is much larger, indicating coalescence as a main mechanism determining the size. Coalescence can be prevented at frother concentrations exceeding the critical coalescence concentration (CCC). The foamability tests indicate that stability of foams under dynamic conditions is determined by bubble coalescence. This study involved multiple reactions and reactants, such as 2-(2-(Hexyloxy)ethoxy)ethanol (cas: 112-59-4Recommanded Product: 2-(2-(Hexyloxy)ethoxy)ethanol).
