Chemical Synthesis	From the waste (liquor) of the wood-pulp industry; vanillin is extracted with benzene after saturation of the sulfite waste liquor with CO2. Vanillin is also derived naturally through fermentation.
storage	Vanillin oxidizes slowly in moist air and is affected by light. Solutions of vanillin in ethanol decompose rapidly in light to give a yellow-colored, slightly bitter tasting solution of 6,6’-dihydroxy- 5,5’-dimethoxy-1,1’-biphenyl-3,3’-dicarbaldehyde. Alkaline solutions also decompose rapidly to give a brown-colored solution. However, solutions stable for several months may be produced by adding sodium metabisulfite 0.2% w/v as an antioxidant. The bulk material should be stored in a well-closed container, protected from light, in a cool, dry place.
Purification Methods	Crystallise vanillin from water or aqueous EtOH, or by distillation in vacuo.[Beilstein 8 IV 1763.]
Incompatibilities	Incompatible with acetone, forming a brightly colored compound. A compound practically insoluble in ethanol is formed with glycerin.
Regulatory Status	GRAS listed. Included in the FDA Inactive Ingredients Database (oral solutions, suspensions, syrups, and tablets). Included in nonparenteral medicines licensed in the UK. Included in the Canadian List of Acceptable Non-medicinal Ingredients.
