General Description

The chemical (R)-2,2',3,3'-Tetrahydro-6,6'-bis(4-nitrophenyl)-1,1'-spirobi[1H-indene]-7,7'-diol, also known as tetrahydro bisphenol A dinitro spirobiindane (TBNPA), is a synthetic compound used as a flame retardant in various industrial applications. It is a white to off-white powder that is insoluble in water but soluble in organic solvents. TBNPA is known for its heat stability and ability to inhibit the ignition and spread of flames. However, concerns have been raised about its potential environmental and health effects, as it has been detected in various environmental media and has been found to be bioaccumulative. Additionally, TBNPA has been classified as a substance of very high concern by the European Chemicals Agency due to its endocrine-disrupting properties.
