The carbon disulfide chemical formula is CS2. Carbon disulfide is also spelt as carbon disulphide. It is a colourless volatile liquid, which is used frequently as a building block in organic chemistry. Being the industrial and chemical non-polar solvent, the formula of carbon disulfide carries various chemical properties, which we will discuss on this page.
Along with this, we will have a look at the molecular formula of carbon disulfide, the structure to understand the carbon disulphide formula.

Now, let’s have a look at the basic reaction for the carbon disulphide formula:
CS2 is a highly inflammable volatile liquid. Its combustion produces sulfur dioxide by reacting with atmospheric gas, i.e., oxygen. Therefore, according to the ideal stoichiometry, the following reaction undergoes:
CS2(l) + 3 O2(g) → CO2(g) + 2 SO2(g)
Here, one mole of CS2 reacts with three moles of O2 to produce CO2 and two moles of SO2.
Conclusion
CS2 is a highly reactive volatile liquid, which is formed as;
C + 2S → CS2
Being a highly flammable gas, it must be stored in a refrigerator at lower temperatures.
