Propanoicacid,2-(4-ethoxyphenoxy)-2-methyl- (cas: 154548-95-5) belongs to ethers. Esters are also usually derived from carboxylic acids. It may also be obtained by reaction of acid anhydride or acid halides with alcohols or by the reaction of salts of carboxylic acids with alkyl halides. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.Recommanded Product: 154548-95-5

A simple synthetic route to 3-phenoxybenzyl 2-methyl-2-(p-substituted phenoxy and thiophenoxy/naphthoxy)propyl ethers, structurally related to ethofenoprox was written by Kumaran, G.;Kulkarni, G. H.. And the article was included in Indian Journal of Chemistry in 1994.Recommanded Product: 154548-95-5 The following contents are mentioned in the article:

Some title compds, e.g., 4-FC6H4OCMe2CH2OCH2C6H4OPh-3, bearing a close structural resemblance to the powerful insecticide MTI-500 (4-EtOC6H4OCMe2CH2OCH2C6H4OPh-3) have been synthesized by a simple route for evaluating their insecticidal properties (data given). This study involved multiple reactions and reactants, such as Propanoicacid,2-(4-ethoxyphenoxy)-2-methyl- (cas: 154548-95-5Recommanded Product: 154548-95-5).
