Methyl 2-methoxy-4-methylbenzoate (cas: 81245-24-1) belongs to esters. Esters typically have a pleasant smell; those of low molecular weight are commonly used as fragrances and are found in essential oils and pheromones. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.HPLC of Formula: 81245-24-1

Synthesis of substituted benzenoids and biphenyls via Diels-Alder cycloaddition of 6-methoxy-2-pyrones was written by Ahmed, Salman A.;Bardshiri, Esfandiar;Simpson, Thomas J.. And the article was included in Tetrahedron Letters in 1988.HPLC of Formula: 81245-24-1 This article mentions the following:

Pyranones I (R1 = alkyl, Ph; R2 = H, Me) were heated with R3C椤氬挵CO2Me (R3 = CO2Me, H) in PhMe to give benzoate esters II. Esters R1CO2Et underwent a Grignard reaction with CH2:CHCHR2Br and the products were converted, in a series of reactions, to I. In the experiment, the researchers used many compounds, for example, Methyl 2-methoxy-4-methylbenzoate (cas: 81245-24-1HPLC of Formula: 81245-24-1).
