Waa maxay Trimethylacetic anhydride CAS 1538-75-6?

Trimethylacetic anhydride waxay ka tirsan tahay fasalka isku-dhafka alkyl anhydride, kaas oo lagu diyaarin karo falcelinta fuuq-baxa ee aashitada valeric. Waxay leedahay fal-celin kiimiko oo aad u sarreysa waxaana badanaa loo isticmaalaa sidii fal-celin acylation ah oo ku saabsan kiimikada isku-darka dabiiciga ah. Waxaa loo isticmaali karaa falcelinta esterification ee alcohols iyo isku-dhafka phenolic.

Codsiga

Trimethylacetic anhydride waxaa loo isticmaalaa sidii falgal acylation iyo esterification, kaas oo ka qayb qaata falgallada acylation iyo esterification ee aniline iyo phenol. Trimethylacetic anhydride waxaa sidoo kale loo isticmaalaa isku-darka oligonucleotide-ka adag iyo kala-soocidda kinetic-ga ee racemic 2-hydroxy - γ - butyrolactone iyo diphenylacetic acid, si loo soo saaro cyano-4, N-tert-butoxycarbonyl piperidine, iyo isku-darka oligonucleotide-ka adag.
