Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. 87-13-8, formula is C10H16O5, Name is Diethyl 2-(ethoxymethylene)malonate. They 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. Formula: C10H16O5.
Shaik, Althaf;Angira, Deekshi;Thiruvenkatam, Vijay research published 《 Insights into supramolecular assembly formation of diethyl aryl amino methylene malonate (DAM) derivatives assisted via non-covalent interactions》, the research content is summarized as follows. The crystal structures of four derivatives of di-Et 2-(((aryl)amino)methylene)malonate (DAM) have been studied by single crystal X-ray diffraction. The mol. structures of all the four derivatives were found to be in co-planar conformation. The detailed anal. of mol. conformation in four derivatives reveals the presence of a common strong intramol. N-H···O hydrogen bonding, forming a ring of graph-set motif S11 (6). The effect of chloro and nitro substitution on their relative strengths of hydrogen bonding are analyzed here. Particularly, in compound 1, addnl. intramol. hydrogen bonding between -NO2 and N-H was observed that results in the formation of another six-membered chelate ring. On the other hand in case of compound 3, we have observed type-I Cl···Cl interaction for the first time in this class of compounds Further, Hirshfeld surface has been generated that is mapped with dnorm shape index and curvedness to summarize the weak interactions and examine the mol. shapes in all four derivatives Effect of nitro (1 and 2) and chloro (3 and 4) substitution on the C···H, N···O and C···O interaction is highlighted in mol. contour and 2D fingerprint plots.
Formula: C10H16O5, Diethyl ethoxymethylenemalonate is a useful research compound. Its molecular formula is C10H16O5 and its molecular weight is 216.23 g/mol. The purity is usually 95%.
Diethyl ethoxymethylidenemalonate is a matrix effect reagent used in analytical chemistry. It is often used as a substrate for the cycloaddition process, which produces malondialdehyde and hydrochloric acid. The UV-absorption of the malondialdehyde can be measured to determine the concentration of the sample. Diethyl ethoxymethylidenemalonate is also used as a dna template in binding constants, where it binds with amines to form complexes that are then analyzed by light emission. It has been shown to have an inhibitory effect on gyrase and trifluoroacetic acid, both enzymes involved in DNA replication., 87-13-8.
