ABSTRACT
Chloronitridoamine (Cl-N-NO2), a newly identified disinfection byproduct, has become a significant concern in water treatment processes. Initially detected as a UV absorbance interference in the 1980s, its structure was only recently identified in late 2024. Chloronitridoamine primarily forms through reactions between chloramine and nitrogenous compounds, and its presence is predicted in chloraminated drinking water supplies, affecting over 100 million people in the United States.
This presentation explores the comprehensive analysis and occurrence of chloronitridoamine in treated drinking water supplies. It will detail the synthetic pathway for obtaining an authentic standard of chloronitridoamine and introduce a robust LC-MS/MS-based analytical method suitable for post-treatment drinking water samples. Additionally, it will examine the co-occurrence of chloronitridoamine with other disinfection byproducts, particularly those resulting from chloramination.
