The Cas Register Number of Trinitromethane is 517-25-9.The chemical synonyms of Trinitromethane (CAS NO.517-25-9) are Trinitromethane ; Methane, trinitro- ; Nitroform ; Trinitromethane ; BRN 1708361 .The molecular structure of Trinitromethane (CAS NO.517-25-9) is.
Shiskov first obtained it as the ammonium salt in 1857. In 1900, Trinitromethane (CAS NO.517-25-9) was discovered that it can be produced by the reaction of acetylene with anhydrous nitric acid. This method did not become the industrial process of choice untill the 20th century.
Trinitromethane (CAS NO.517-25-9) is used as explosives and rocket fuel and in the manuf of explosive and propellant.
It is derived by the reaction of acetylene and nitric acid.

Trinitromethane (CAS NO.517-25-9) forms a series of bright yellow ionic salts. Many of these salts tend to be unstable and can be easily detonated by heat or impact. Because aqueous solutions of trinitromethane are quite acidic, this poses a handling danger similar to that of picric acid due to corrosion of iron or aluminum surfaces.
