FAQ
Frequently Asked Questions
Many of its derivatives, especially organothiophosphates, are highly toxic and used as nerve agents or pesticides. The pure acids require careful handling in a laboratory setting.
Primarily as a chemical intermediate in the synthesis of organophosphorus compounds for use as pesticides, lubricant additives, and flame retardants.
Thiophosphoric acid has one or more sulfur (S) atoms in place of oxygen (O) atoms in the phosphoric acid (H3PO4) structure, altering its chemical reactivity.
No, it refers to a family of compounds. Common examples include monothiophosphoric acid (H3PO3S) and dithiophosphoric acid (H3PO2S2), depending on how many oxygen atoms are replaced.
