The invention provides methods of preparing 8-hydroxy-2,2,14,14-tetramethylpentadecanedioic acid and methods of making a pharmaceutical material comprising a purified amount of 8-hydroxy-2,2,14,14-tetramethylpentadecanedioic acid. Also provided are compositions and pharmaceutical materials including a purified amount of 8-hydroxy-2,2,14,14-tetramethylpentadecanedioic acid as well as methods of treating various diseases and conditions using the compositions and pharmaceutical materials.

New diamine monomers bearing sulfone terminated pendant groups, as well as methods for making the same, are provided. The diamine monomers are useful toward making polyamide, polyimide, and poly(amide-imide) polymers and copolymers, which possess hygromorphic properties and demonstrate humidity driven motility.
