| titleOfInvention | Alkali metal salts and alkaline earth metal salts of n-isonicotinylhydrazine n-glucuronide and a process for their production |
| abstract | The invention comprises alkali and alkaline-earth metal salts of N-isonicotinylhydrazine N1-glucoronide having the formula <FORM:0876607/IV (b)/1> wherein M represents an alkali metal or one equivalent of an alkaline-earth metal, and the preparation thereof by reacting an alkali or alkaline-earth metal salt of glucuronic acid with isonicotinic acid hydrazide. Preferably the process is carried out at 70-80 DEG C. and a lower aliphatic alcohol is added, such that the alcohol concentration of the solution is 50-80%, to induce crystallisation. Examples describe the preparation of the sodium and calcium salts of N-isonicotinylhydrazide N1-glucuronide, either methanol or ethanol being added to induce crystallisation of the salts. |
