He aha te Trimethylacetic anhydride CAS 1538-75-6?

Ko te trimethylacetic anhydride no te karaehe o nga pūhui alkyl anhydride, ka taea te whakarite ma te tauhohenga matewai o te waikawa valeric. He tino kaha te tauhohenga matū, ka whakamahia hei reagent acylation i roto i te mara o te matū whakahiato waro. Ka taea te whakamahi mo nga tauhohenga esterification o te waipiro me te pūhui phenolic
