Glycerides are fatty acid esters of glycerol; they are important in biology, being one of the main classes of lipids and comprising the bulk of animal fats and vegetable oils. 87-13-8, formula is C10H16O5, Name is Diethyl 2-(ethoxymethylene)malonate. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Category: esters-buliding-blocks.
Coughlin, Omar;De Bruyn, Nathan;Kilgour, David P. A.;Benjamin, Sophie L. research published 《 Crystal Structure and Hirshfeld Surface Analysis of Diethyl (6-methyl-2-pyridyl)aminoethylenemalonate》, the research content is summarized as follows. The title compound, di-Et (6-methyl-2-pyridyl)aminoethylenemalonate (1), crystallizes in the monoclinic space group P21/c (Number 14). The unit cell parameters are a = 10.5657(7) Å, b = 9.1784(5) Å, c = 14.5681(7) Å, β = 101.636(6)°, Z’ = 1 and Z = 4 at 150 K. The extended structure forms approx. orthogonal columns of stacked mols. All bond lengths and angles are unremarkable. No disorder, twinning or co-crystallized solvent is present in the structure. An intramol. hydrogen bond exists between the enamine nitrogen and carbonyl oxygen. Hirshfeld surface anal. reveals a short contact between a carbonyl oxygen and neighboring aryl hydrogen, as well as a carbonyl-carbonyl interaction.
Category: esters-buliding-blocks, 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.
