Pyrene-1,3,6,8-Tetrasulfonic Acid Tetrasodium Salt
Pyrene-1,3,6,8-tetrasulfonic acid tetrasodium salt (PTSA, CAS 59570-10-0) is an organic fluorescent compound with a pyrene core substituted by four sulfonate groups, formula C₁₆H₆Na₄O₁₂S₄ and MW 610.43. It exhibits intense blue fluorescence under UV excitation and is used as an inert fluorescent tracer in industrial aqueous systems. Note: the tetrasodium salt is also commonly associated with CAS 59572-10-0.
• Cooling tower water systems: inert fluorescent tracer for chemical treatment dosage monitoring.
• Boiler feed water monitoring: leak detection and fluid retention-time evaluation.
• Oilfield secondary recovery: subterranean water flow mapping and injection dynamics.
• Wastewater tracking: dispersion patterns and dilution rates in natural water bodies.
