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 white to almost white.

11.2.3 Test of Clarity & Colour:

Dissolve 5 g of the sample in 100 ml of distilled water; the solution should be clear and colourless.

11.2.4 Test of pH

Weigh accurately on analytical balance 5 g 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 30°C on pH meter; it should be 5.2 to 6.5 at 20°C to 25°C.

11.2.5 Test of Test of Solubility:

Check the solubility of the sample in Water and Chloroform.
It should be freely soluble in Chloroform and sparring soluble in water

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 be between 3.5 to 5.5%.

11.2.7 Water Contents:

Weigh accurately 50mg of sample and titrate for Karl Fischer water determination it should be between 4 to 5.5%.

11.2.8 Melting Point:

Check the melting point of sample; it should be about 125°C with decomposition.

11.3 Record the result of Physical Analysis on quality report.
