The bromine number is used as a method of determining the unsaturation in typical hydrocarbon molecules.

The bromine number is the number of grams of bromine absorbed by 100 g of oil which indicates the percentage of double bonds in the material. The number is an indicator of the unsaturated constituents in a liquid fuel. In the test method, a known weight of the sample dissolved in a specified solvent maintained at 0 to 5°C (32 to 41°F) is titrated with standard bromide-bromate solution. However, the determination of the end point is method dependent.
