3-Deacetyl-3-butanoyl acebutolol hydrochloride is a racemic mixture of two enantiomers, (+)-(S)-3-Deacetyl-3-butanoyl acebutolol and (-)-(R)-3-Deacetyl-3-butanoyl acebutolol. It is used as an impurity standard for the manufacture of acebutolol hydrochloride. The substance has a purity of at least 99% by HPLC. 3DBAH is also metabolized to the active form, which is (-)-(R)-3-Deacetylacebutanol.

Applications 3-Dehydroxy 2,3-Dehydro Atorvastatin Lactone is an intermediate in the preparation of Atorvastatin (A791750) and it’s derivatives.

1-[(1-Methylethyl)amino]-3-phenoxy-2-propanol is an organic compound that belongs to the class of phenoxyethanol derivatives. It has been used in milligram amounts to assist in the separation of racemic mixtures by countercurrent chromatography. The compound is a racemate and the enantiomers are separated by chiral high performance liquid chromatography. The β-adrenergic agonist activity of 1-[(1-methylethyl)amino]-3-phenoxy-2-propanol has been shown in rats.
