Provided is a method for reprocessing neuromuscular blocking agents containing a quaternary ammonium salt, e.g., Rocuronium bromide, using a novel dealkylation method. The process is effective in obtaining a highly pure product from a contaminated starting material by heating, optionally in the presence of an organic solvent, to produce a dealkyated product. The dealkylated product is purified, e.g., by crystallization, and converted by any known method to a stable, highly-pure neuromuscular blocking agent.
