| Questions And Answer | Back Directory | [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.

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]
