Saccharin is primarily produced in two types i.e. soluble and insoluble saccharin. The soluble saccharin (in water) is called Sodium Saccharin whereas insoluble saccharin is called Insoluble Saccharin.
Saccharin is produced in two physical forms, viz granular and powder
Saccharin is used in a variety of industry such as food and beverage, personal care products, table top sweetener, electroplating brighteners, pharmaceuticals etc.
Sodium Saccharin or Soluble Saccharin:
Sodium saccharin is the salt form of saccharin, an artificial sweetener. Saccharin sodium is a type of artificial sweetener that is sweeter than sucrose but has a bitter aftertaste. Saccharin sodium is often used to sweeten soft drinks, candy, biscuits, medicine and toothpaste.

First identificationiB, E.
Second identificationiA, C, D, E.
A. Melting point: 226C to 230C.
To 5 ml of solution S (see Tests) add 3 ml of dilute hydrochloric acid. A white precipitate is formed. Filter and wash with water. Dry the precipitate at 100-105 °C.
B. Infrared absorption spectrophotometry.
C. Mix about 10 mg with about 10 mg of resorcinol, add 0.25 ml of sulphuric acid and carefully heat the mixture over a naked flame until a dark green colour is produced. Allow to cool, add 10 ml of water and dilute sodium hydroxide solution until an alkaline reaction is produced. An intense green fluorescence develops.
D. To 0.2 g add 1.5 ml of dilute sodium hydroxide solution, evaporate to dryness and heat the residue carefully until it melts, avoiding carbonisation. Allow to cool, dissolve the mass in about 5 ml of water, add dilute hydrochloric acid until a weak acid reaction is produced and filter, if necessary. To the filtrate add 0.2 ml of ferric chloride solution. A violet colour develops.
E. Solution S gives reaction (a) of sodium.
Solution S: Dissolve 5.0 g in carbon dioxide-free water and dilute to 50.0 ml with the same solvent.
Appearance of solution: The solution is clear and colourless.
Dissolve 5.0 g in 25 ml of carbon dioxide-free water.
Acidity or alkalinity: To 10 ml of solution S add about 0.05 ml of a 10 g/l solution of phenolphthalein in ethanol (96 per cent). The solution is not pink. Add 0.1 ml of sodium hydroxide 0.1 M. The solution becomes pink.
o- and p-Toluenesulphonamide: Gas chromatography to pass the test.
Readily carbonisable substances: Dissolve 0.20 g in 5 ml of sulphuric acid and keep at 48-50C for 10 min. When viewed against a white background, the solution is not more intensely coloured than a solution prepared by mixing 0.1 ml of red primary solution, 0.1 ml of blue primary solution and 0.4 ml of yellow primary solution with 4.4 ml of water.
Heavy metals: Maximum 20 ppm.
Water: Maximum 15.0 per cent, determined on 0.200 g.
Dissolve 0.150 g in 50 ml of anhydrous acetic acid, with slight heating if necessary. Titrate with 0.1 M perchloric acid, determining the end-point potentiometrically. Carry out a blank titration. 1 ml of 0.1 M perchloric acid is equivalent to 20.52 mg of C7H4NNaO3S.
In an airtight container.

Sodium Saccharin occurs as white crystals or as a white, crystalline powder. In powdered form, it effloresces to the extent that it usually contains only about one-third the amount of water indicated in its molecular formula. One gram is soluble in 1.5 mL of water and in about 50 mL of alcohol.
Function: Nonnutritive sweetener.
A. Dissolve about 100 mg of sample in 5 mL of a 1:20 solution of sodium hydroxide, evaporate to dryness, and gently fuse the residue over a small flame until ammonia no longer evolves. After the residue has cooled, dissolve it in 20 mL of water, neutralize the solution with 2.7 N hydrochloric acid, and filter. Add 1 drop of ferric chloride to the filtrate. A violet color appears.
B. Mix 20 mg of sample with 40 mg of resorcinol, cautiously add 10 drops of sulfuric acid, and heat the mixture in a liquid bath at 200C for 3 min. After cooling, add 10 mL of water and an excess of 1 N sodium hydroxide. A fluorescent green liquid results.
C. The residue obtained by igniting a 2-g sample gives positive tests for Sodium.
D. Add 1 mL of hydrochloric acid to 10 mL of a 1:10 aqueous solution. A crystalline precipitate of saccharin forms. Wash the precipitate well with cold water, and dry at 105C for 2 h. The saccharin thus obtained melts between 226C and 230C.
