Definition

ChEBI: Glyconiazide is an aromatic carboxylic acid and a pyridinemonocarboxylic acid.

Manufacturing Process

2 Methods of producing of d-glucuronolactone isonicotinyl hydrazone:
1. To 88.0 g of D-glucuronolactone, in the bottom of a 3 L round bottom flask, was added 1.5 liters of methyl alcohol (acetone-free). The mixture was boiled gently on a steam bath for 10 min, producing a clear solution. To this hot solution, 70.0 g of isonicotinic acid hydrazide was added all at once. The mixture was then boiled vigorously for 10 min and the clear solution filtered without suction through a piece of lens paper into a two liter Erlenmeyer flask. After the flask had been allowed to stand 24 h at room temperature, crystals in the form of beautiful white rods and narrow plates were observed. These crystals were filtered with suction, washed with a small amount of methyl alcohol, and sucked to complete dryness. The resulting product was dried in a vacuum desiccator for 3 days. Actual yield was 148.0 g, (yield of better than 99%). On heating the d-glucuronolactone isonicotinyl hydrazone thus formed, the crystals charred and decomposed with foaming between 150° and 160°C without any sharp melting point. The new compound was already very pure, and upon recrystallization from a large amount of methyl or ethyl alcohol (absolute) showed no appreciable change in physical properties from the unrecrystallized product.
2. D-Glucuronic acid was liberated from a solution of its sodium salt (12.0 g) in water (25 ml) by the addition of concentrated hydrochloric acid (5 ml). To the mixture, sodium acetate (5.0 g) was added to remove the excess of the mineral acid. Isonicotinic acid hydrazide (7.0 g) was then introduced into the clear solution and mixing accomplished by thorough shaking. Methyl alcohol (250 ml) was added and the mixture boiled on a steam bath for 10 min. A white crystalline precipitate started to separate from the solution after a few minutes heating and was allowed to stand overnight at room temperature before filtering. The crystals (white small rods) were sucked to dryness, washed with a small amount of absolute methanol and again sucked to dryness. The product was further dried in a vacuum desiccator for 24 h. Yield: 25-50%. The hydrazone melted at 150°-160°C (dec.).
