Formula & Methodology
The degree of unsaturation (DUS) can be calculated using the formula:
DUS = (2 * C + 2 * N + P – H / 2) – (O / 2) – (S / 2) + (Halogen / 2)
Where C, N, P, H, O, S, and Halogen represent the number of carbon, nitrogen, phosphorus, hydrogen, oxygen, sulfur, and halogen atoms in the molecular formula, respectively.

Interactive FAQ
What is the difference between degree of unsaturation and index of hydrogen deficiency?
The degree of unsaturation is a measure of the number of double bonds or rings in a molecule, while the index of hydrogen deficiency is a measure of the number of hydrogens missing from the molecule to make it fully saturated.
