Abstract
Novel and very useful forms of sodium (S)-2-(6-methoxy-2-naphthyl)propionate are provided. These forms are sodium (S)-2-(6-methoxy-2-naphthyl)propionate monohydrate having an average particle size significantly larger than about 70 microns--the size of conventional sodium (S)-2-(6-methoxy-2-naphthyl)propionate--and a chiral purity of at least 98% (S)-enantiomer. Process technology enabling the production of such novel products is also described. The provision of such novel products makes possible significant improvements in processing time, plant capacity and product handling operations.
