Formaldehyde Solution BP Ph Eur
Formalin
Formaldehyde Solution (35 per cent), Ph Eur
CH2O -- 30.03 -- CAS 50-00-0
Action and use: When suitably diluted, used in the treatment of warts.

DEFINITION
Content: 34.5 per cent m/m to 38.0 per cent m/m of formaldehyde (CH2O; Mr 30.03). It contains methanol as stabiliser.

CHARACTERS
Appearance: Clear, colourless liquid.
Solubility: Miscible with water and with ethanol (96 per cent). It may be cloudy after storage.

IDENTIFICATION
A. Dilute 1 ml of solution S (see Tests) to 10 ml with water. To 0.05 ml of the solution add 1 ml of a 15 g/l solution of chromotropic acid sodium salt, 2 ml of water and 8 ml of sulphuric acid. A violet-blue or violet-red colour develops within 5 min.
B. To 0.1 ml of solution S add 10 ml of water. Add 2 ml of a 10 g/l solution of phenylhydrazine hydrochloride, prepared immediately before use, 1 ml of potassium ferricyanide solution and 5 ml of hydrochloric acid. An intense red colour is formed.
C. Mix 0.5 ml with 2 ml of water and 2 ml of silver nitrate solution in a test-tube. Add dilute ammonia until slightly alkaline. Heat on a water-bath. A grey precipitate or a silver mirror is formed.
D. It complies with the limits of the assay.

TESTS
Solution S: Dilute 10 ml, filtered if necessary, to 50 ml with carbon dioxide-free water.
Appearance of solution: Solution S is colourless.
Acidity: To 10 ml of solution S add 1 ml of PhPh solution. Not more than 0.4 ml of 0.1 M sodium hydroxide is required to change the colour of the indicator to red.
Methanol: To pass Gas chromatography.
Sulphated ash: Maximum 0.1 per cent, determined on 1.0 g.

Formaldehyde Solution in bulk containers contains not less than 37.0 percent, by weight, of formaldehyde (CH2O), with methanol added to prevent polymerization. Formaldehyde Solution in small containers (4 liters or less) contains not less than 36.5 percent, by weight, of formaldehyde (CH2O), with methanol present to prevent polymerization.

Labeling: The label of bulk containers of the Solution directs the drug repackager to demonstrate compliance with the USP Assay limit for formaldehyde of not less than 37.0%, by weight, immediately prior to repackaging.

Identification:
A: Dilute 2 mL with 10 mL of water in a test tube, and add 1 mL of silver-ammonia-nitrate: metallic silver is produced either in the form of a finely divided, gray precipitate, or as a bright, metallic mirror on the sides of the test tube.
B: Add 2 drops to 5 mL of sulfuric acid in which about 20 mg of salicylic acid has been dissolved, and warm the liquid very gently: a permanent, deep-red color appears.
