11.2 PHYSICAL ANALYSIS USP/BP

11.2.1 Test of Physical Form:

Check the sample and confirm its physical form; it should be crystalline powder.

11.2.2 Test of Colour:

Confirm the colour of the material by comparing with standard from colour chart; it should be yellow.

11.2.3 Test of Odour:

Check the odour of the sample; it should be odourless or almost odourless.

11.2.4 Test of Solubility:

Check the solubility of the sample in water, ethanol and Chloroform.
It should be slightly soluble in water, chloroform and ethanol.

11.2.5 Test of pH:

Weigh accurately on analytical balance 5 mg of sample and make the volume upto 100 ml with distilled water. Take 50 ml from the resulting solution and measure the pH of solution at 20°C to 25°C on pH meter; it should be 4.5 to 7.0 at 20°C to 25,C.

11.2.6 Test of loss on drying:

Weigh accurately 10 g of sample on moisture balance. Adjust the temperature at 105°C, start drying the sample. At the end balance show percentage loss of moisture; moisture contents should not be more than 0.5%.

11.3 Record the result of Physical Analysis on quality report.

11.4 CHEMICAL ANALYSIS: USP/BP

11.4.1 Examination of Furazolidone by IR spectrum:

Take dried sample to 5mg of Furazolidone and thoroughly mix with 95mg of dried standard of potassium bromide in pastel mortar.

Fill Macro cups with provided funnel like instrument and draw the spectrum it should be complies the standard spectrum.

11.4.2 Identification Test of Furazolidone:

Dissolve 1mg in 1ml of dimethylformamide and add 0.05ml of IM ethanolic potassium hydroxide. A deep blue colour is produced.

11.4.3 Contents of Furazolidone:

Carryout the assay procedure protected from light.

11.4.3.1 Sample Preparation:

11.4.3.1.1 Weigh accurately on analytical balance 100 mg of the powdered sample of Furazolidone, add 150ml dimethylformamidae, swirl to dissolve and make the volume upto 500 ml with water in the volumetric flask.
