R-salt (TNX, systematic name hexahydro-1,3,5-trinitroso-1,3,5-triazine) is an explosive organic compound that has been used in terrorist attacks.{{cite web | last=Lowrey | first=Erin | title=New Orleans terror attack suspect made rare compound, NBC reports | website=WDSU | date=2025-01-05 | url=https://www.wdsu.com/article/new-orleans-terror-attack-new-explosive-compound/63333833 | access-date=2025-01-12}}{{cite journal |doi=10.1002/prep.202400028 |title=A comprehensive study on the thermal properties and chemical characterization of 1,3,5-trinitroso-1,3,5-triazine (R-Salt) |date=2024 |last1=Wilkins |first1=Benjamin |last2=Sartain |first2=Hope T. |last3=Schneidereit |first3=Sheana |last4=Ostrow |first4=Benjamin |last5=Aparicio |first5=Joaquin |last6=Horan |first6=Andrew |last7=Pedersen |first7=Kevin |last8=Barber |first8=Jeffrey |last9=Perez |first9=Johnny |last10=Richard |first10=Marc |last11=Pollock |first11=Elizabeth |last12=Brady |first12=John |journal=Propellants, Explosives, Pyrotechnics |volume=49 |issue=6 }} It is a high explosive that is less sensitive than other compounds of similar availability. It has a similar structure to RDX but with nitrosamine groups replacing the nitroamine groups of RDX. It is also found as a decomposition product of RDX in the environment, such as after RDX detonation.{{cite journal |doi=10.1002/prep.201600149 |title=An Improved Process Towards Hexahydro-1,3,5-trinitroso-1,3,5-triazine (TNX) |date=2017 |last1=Rothstein |first1=Sarah A. |last2=Dubé |first2=Pascal |last3=Anderson |first3=Stephen R. |journal=Propellants, Explosives, Pyrotechnics |volume=42 |issue=2 |pages=126–130 }} This may be a potential environmental issue as a study concluded that TNX is toxic to earthworm Eisenia fetida.{{cite journal | last1=Zhang | first1=Baohong | last2=Kendall | first2=Ronald J. | last3=Anderson | first3=Todd A. | title=Toxicity of the explosive metabolites hexahydro-1,3,5-trinitroso-1,3,5-triazine (TNX) and hexahydro-1-nitroso-3,5-dinitro-1,3,5-triazine (MNX) to the earthworm Eisenia fetida | journal=Chemosphere | publisher=Elsevier BV | volume=64 | issue=1 | year=2006 | issn=0045-6535 | doi=10.1016/j.chemosphere.2005.11.037 | pages=86–95| pmid=16403555 | bibcode=2006Chmsp..64...86Z }} R-salt is synthesized by nitrosation of hexamine.
