  • Manufacture of pure hydralazine salts
    Publication number: 20070129546
    Abstract: The present invention provides an improved process of preparing hydralazine hydrochloride, which involves the preparation of 1-chlorophthalazine salt and further reacting with hydrazine followed by purification of hydralazine hydrochloride, which is free of phosphate, does not contain any individual impurities more than 0.05%, total impurities less than 0.5%, and a hydrazine content of not more than 0.001%, and preferably less than 0.0003%. One benefit of improved purity is enhanced storage stability.

  • Process of making optically pure L-pipecolic acid and process of making anesthetics and intermediates therefrom
    Publication number: 20060276654
    Abstract: The present invention describes a novel process of preparation of optically pure L-Pipecolic acid and an improved process for the conversion of L-pipecolic acid to L-N-(2,6-dimethylphenyl)-1-propyl-2-piperidinocarboxamide, its hydrochloride salt and hydrochloride monohydrate.

  • Novel process for preparation of isotonic aqueous injection of ropivacaine
    Publication number: 20060270708
    Abstract: The preparation of an injectable solution of ropivacaine by dissolving ropivacaine base in aqueous acidic solution having a molar ratio of acid to ropivacaine base greater than 1:1 eliminates the need for a hydrochloride or hydrochloride monohydrate intermediate in the manufacture of the injectable. The osmolality can be adjusted as needed. The excess acid is neutralized with a base.
