Ester amapangidwa kuchokera ku esterization reaction ya inorganic acid kapena organic acid kapena mowa.Mowa kapena phenol kapena acidic anhydride, mowa ndi ethylene, acidic acid yaulere ndi mafuta otumphukira a nayitrogeni amathanso kupanga ester.Hydrojeni pa alpha-carbon mu mamolekyu a ester amataya mowa wa molekyulu ndi ester ina ya molekyulu pansi pamikhalidwe yamchere kuti apange β-keto ester, yomwe imatchedwa ester contraction reaction.Mwachitsanzo, acetyl acetate amapangidwa kuti apange acetyl ethyl acetate.Zimenezi n'zofunika kwambiri organic synthesis.

Dzina la ester limachokera ku dzina lofanana la carboxylic acid ndi mowa kapena phenol, monga "acid inayake ndi ester".Circle esters amatchedwa lactone (lactone).Mankhwala a ester ndi ofanana ndi amyl niche anhydride, omwe amatha ku hydrolysis, mowa ndi ammonia.Ma ester otsika ndi onunkhira komanso osasunthika opanda mtundu, ndipo ester yapamwamba ndi yolimba.Estes ndi zosungunulira zofunika komanso zopangira zopangira, ndipo ma ester ena ndi mankhwala okha.Malingana ndi mtundu wa asidi, ester ikhoza kugawidwa mu inorganic acid ester ndi organic acid ester.Etate, ethyl acetate ndi mafuta ester, acetate ndi ester onunkhira, ndipo namanonate ndi ester yozungulira.
