1 Description White to almost White Crystalline Powder
2 Solubility Practically insoluble in water, sparingly soluble in methylene chloride, slightly soluble in alcohol and in methanol.
3 Identification1. Melting Point2. By UV3. By IR4. By TLC5. Chemical test 1. Between 169 0C to 174 0C 2. The sample solution should show a maximum at 300 nm and a less intense maximum absorbance at 275 nm. The specific absorbance at the maxima should be 61 to 65 and 27 to 32 respectly.3. IR spectrum of sample should be concordant with that of glibenclamideworking standard.4. The Principal spot obtained with the test solution should be Similar in position and size to the principal spot obtained in the chromatogram obtiained with the reference solution.5. The sample solution should show blue fluorescence in ultraviolet light at 365 nm. Dislove 0.1 gm of chloral hydrate in solution, within 5 min. , the colour should change to deep yellow, and after 20 min develops a brownish tinge
