Descrição geral
1,1,1-Trichloro-2-methyl-2-propanol hemihydrate (chlorobutanol) converts benzisoxazole to α-aryloxyisobutyric acid. 1,1,1-Trichloro-2-methyl-2-propanol hemihydrate (chlorobutanol) forms eutectic with dimethyl sulfone, which is the most suitable media for freeze-drying due to its high solubilizing ability and a good rate of solvent removal.
Aplicação
1,1,1-Trichloro-2-methyl-2-propanol (chlorobutanol) is a preservative that can be quantified using capillary electrophoretic method.

Miniaturization of active implantable medical devices is currently compromised by the available means for electrically powering them. Most common energy supply techniques for implants--batteries and inductive couplers--comprise bulky parts which, in most cases, are significantly larger than the circuitry they

A practical synthesis of benzisoxazole 1 and its conversion to alpha-aryloxyisobutyric acid 2 using 1,1,1-trichloro-2-methyl-2-propanol (chloretone) was developed. Benzisoxazole 1 was formed in high yields by the action of either methanesulfonyl chloride/base upon intermediate oxime 8 or with thionyl chloride/base
