PHYSICAL ANALYSIS USP/BP/Inhouse
Test of Physical Form:

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

Test of Colour:

Confirm the colour of the material by comparing with standard from colour chart; it should be white to almost while. How To Test Cloxacillin Sodium

Test of Clarity & Colour:

Weigh accurately on analytical balance 100 mg of sample, put it in the test tube, and dissolve it in 10 ml of distilled water; it should be clear and colourless. How to Test Cloxacillin Sodium

Test of pH:

Weigh accurately on analytical balance 10 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 25°C2° on pH meter; it should be 5.0 to 7.0 at 25°C 2°.

Test of Moisture Contents

Weigh accurately 10 g of sample on moisture balance. Adjust the temperature at 85°C, start drying the sample. At the end balance show percentage loss of moisture; moisture contents should not be more than 5%.

Water Contents:

Weigh accurately 50mg of sample and titrate for Karl Fischer water determination it should be between 3 to 4.5%.

Test of Solubility:

Check the solubility of the sample in water, methanol and ethanol.
It should be freely soluble in water, methanol and soluble in Ethanol.

Bulk Density:

Take sample in the measuring cylinder, the surface level of the sample in the cylinder should be even, note the volume without tapping, it should be between 0.400 – 0.600 g/ml.

Tapped Density:

Take sample in the measuring cylinder, the surface level of the sample in the cylinder should be even, note the volume with tapping, it should be between 0.450 – 0.800 gm/ml.
Record the result of Physical Analysis on quality report.

CHEMICAL ANALYSIS: USP/BP/Inhouse
Examination of Cloxacillin by IR spectrum:

Take dried sample to 5mg of Cloxacillin sodium 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.

Identification Test of Cloxacillin:

Weigh accurately on analytical balance 20 mg of the sample, put it in the test tube, add 0.5 ml of distilled water, 0.5 ml of Conc. Sulphuric Acid; slightly greenish yellow colour appears.

Identification Test of Sodium:

Make the paste of 500 mg of the sample with 0.5 ml of concentrated hydrochloric acid, Moisten the platinum wire with the paste and introduce into the flame of a Bunsen Burner; golden yellow colour flame should produce.

Contents of Cloxacillin Sodium

Standard Preparation:

Weigh accurately on analytical balance reference standard Cloxacillin Sodium equivalent to 100 mg of Cloxacillin Sodium, add 10 ml of Methanol, mix it for 15 minutes, make the volume upto 50 ml with Methanol in volumetric flask and filter it in 100 ml titration flask.
Take 2 ml from the step 11.4.4.1.1 and make the volume upto 100 ml with 0.1 N Sulphuric Acid.
