tert-Butyl acetoacetate Chemical Properties,Usage,Production

Description Tert-Butyl acetoacetate is a reagent used to acetoacetylate hydroxyl-bearing coatings resins, such as polyesters, acrylics, cellulosics, and epoxies. It can be used as an acetoacetylating reagent in pharmaceutical, agrichemical, and pigment applications. It is used as an intermediate for the syntheses of different organic chemicals. For instance, it may be used to synthesize various acetoacetic acid derivatives, acetoacetates, acetoacetamides, 1-(diethylamino)-2-acetoacetoxypropane, (S)-tert-butyl 3-hydroxybutyrate, benzothiazole β-keto ester derivatives, and 3,4-disubstituted pyrroles.
Chemical Properties liquid
Uses Intermediate for the syntheses of different organic chemicals. Product Data Sheet
Uses tert-Butyl acetoacetate is used as intermediate for the syntheses of different organic chemicals. Raw material in pharmaceutical Industry, In agrochemical industry. Reagent for Acyloin synthesis and ?,β - unsaturated ketones synthesis.
General Description tert-Butyl acetoacetate (t-BAA) is a cheap and easy to store commercial reagent. Reaction demonstrated that the more hindered tert-butyl acetoacetate (t-BAA, la) is ca.15-20-fold more reactive than the more commonly used methyl or ethyl analogs. It is widely employed as an acetoacetylating reagent.
Flammability and Explosibility Flammable
Biochem/physiol Actions β-Actin modulates cell growth, migration and the G-actin pool. Mutations in ACTB leads to pleiotropic developmental disorder.
Purification Methods Distil it under reduced pressure through a short column. [Lawesson et al. Org Synth Coll Vol V 155 1973, Lawesson et al. Org Synth 42 28 1962, Beilstein 3 IV 1536.] HARMFUL VAPOUR.
