Diphosphorus is an inorganic chemical with the chemical formula P 2.Unlike nitrogen, its lighter pnictogen neighbor which forms a stable N 2 molecule with a nitrogen to nitrogen triple bond, phosphorus prefers a tetrahedral form P 4 because P-P pi-bonds are high in energy.

White phosphorus (left), red phosphorus (center left and center right), and violet phosphorus (right) White phosphorus and resulting allotropes Elemental phosphorus can exist in several allotropes, the most common of which are white and red solids.
Facilities with these designations are also sometimes given as P1 through P4 (for pathogen or protection level), as in the term P3 laboratory. [ 5 ] At the lowest level of biosafety, precautions may consist of regular hand-washing and minimal protective equipment.

An overview of the different components included in the field of chemical biology. Chemical biology is a scientific discipline between the fields of chemistry and biology.The discipline involves the application of chemical techniques, analysis, and often small molecules produced through synthetic chemistry, to the study and manipulation of biological systems.

Phosphorus tetroxide can be produced by thermal decomposition of phosphorus trioxide, which disproportionates above 210 °C to form phosphorus tetroxide, with elemental phosphorus as a byproduct:
