DIBUTYL OXALATE is a dicarboxylic acid.
DIBUTYL OXALATE has clear colorless liquid with a butyl-like odor.
DIBUTYL OXALATE belongs to the class of organic compounds known as dicarboxylic acids and derivatives. 
Dicarboxylic acids and derivatives are organic compounds containing exactly two carboxylic acid groups. 
DIBUTYL OXALATE has been detected, but not quantified in, several different foods, such as black tea, nuts, teas (Camellia sinensis), green tea, and herbal tea.
This could make DIBUTYL OXALATE a potential biomarker for the consumption of these foods.
DIBUTYL OXALATE is a colourless, crystalline, toxic organic compound belonging to the family of dicarboxylic acids. 
DIBUTYL OXALATE occurs in the form of DIBUTYL OXALATEs metal salts (usually calcium or potassium) in many plants. 
DIBUTYL OXALATE is commercially manufactured by heating sodium formate in the presence of an alkali catalyst to form sodium oxalate, which should be converted to free oxalic acid when treated with sulfuric acid. 
DIBUTYL OXALATE is also prepared by oxidizing carbohydrates with nitric acid, by heating saw dust with caustic alkalies or by fermentation of sugar solutions in the presence of certain molds. 
DIBUTYL OXALATE is the only possible compound in which two carboxyl groups are joined directly; for this reason oxalic acid is one of the strongest acids in organic compounds. 
Unlike other carboxylic acids, oxalic acid (and formic acid) is readily oxidized and combine with calcium, iron, sodium, magnesium, or potassium to form less soluble salts called oxalates.
