Trimethyl orthoformate yog qhov yooj yim orthoester. Nws yog cov tshuaj reagent siv hauv cov organic sib txuas rau kev qhia txog pab pawg tiv thaiv rau aldehydes. Cov khoom ntawm cov tshuaj tiv thaiv ntawm aldehyde nrog trimethyl orthoformate yog acetal. Feem ntau, cov tshuaj acetal no tuaj yeem tiv thaiv tsis tau rov qab mus rau aldehyde los ntawm kev siv cov tshuaj hydrochloric.Qhov kev tsim ua ke ntawm cov tshuaj no yog los ntawm hydrogen cyanide thiab methanol.Trimethyl orthoformate yog lub tsev tsim muaj txiaj ntsig zoo rau tsim methoxymethylene pawg thiab heterocyclic ring systems. Nws qhia cov pab pawg formyl rau cov txheej txheem nucleophilic, piv txwv li RNH2 los tsim R-NH-CHO, uas tuaj yeem ua rau muaj kev cuam tshuam ntxiv. Nws tau siv los tsim cov tshuaj tua kab, azoxystrobin thiab picoxystrobin, ntxiv rau qee tus tswv cuab ntawm tsev neeg floxacin ntawm cov tshuaj tua kab mob. Ib tug xov tooj ntawm cov kws kho mob nruab nrab kuj tseem ua los ntawm trimethyl orthoformate.
