Abstract

Aspects of the disclosure include crystalline solids of 3-palmitoyl-amido-1,2-propanediol and 3-palmitoyl-amido-2-hydroxy-1-dimethoxytriphenylmethylether-propane. Methods for preparing the crystalline solids of 3-palmitoyl-amido-1,2-propanediol and single crystals of 3-palmitoyl-amido-2-hydroxy-1-dimethoxytriphenylmethylether-propane are also provided. Methods for preparing a 3-palmitoyl-amido-2-hydroxy-1-dimethoxytriphenylmethylether-propane from a crystalline solid of 3-palmitoyl-amido-1,2-propanediol are also described.
