General description
2-Chloro-6-(trichloromethyl)pyridine is a chlorinatedheterocyclic compound that belongs to the pyridine family and serves as an active ingredient found in commercially available nitrogen stabilizers. Iteffectively delays the conversion of ammonium (NH₄⁺) to nitrate (NO₃⁻). This process enhances nitrogen retention and improves nitrogen use efficiency,ultimately leading to increased crop yields.
Application
- Biological and chemical nitrification inhibitors exhibited different effects on soil gross N nitrification rate and N(2)O production: a (15)N microcosm study.: This study examines the effects of biological and chemical nitrification inhibitors, including 2-Chloro-6-(trichloromethyl)pyridine, on soil nitrogen processes. The findings highlight the differential impacts on soil nitrogen dynamics and greenhouse gas emissions (Lan et al., 2023).
- Nitrous oxide emissions from manured soils as a function of various nitrification inhibitor rates and soil moisture contents.: This paper explores the relationship between nitrification inhibitor application rates, including 2-Chloro-6-(trichloromethyl)pyridine, and soil moisture on nitrous oxide emissions, providing insights into optimizing inhibitor use for environmental benefits (Lin and Hernandez-Ramirez, 2020).
- Nitrate losses in subsurface drainage from a corn-soybean rotation as affected by fall and spring application of nitrogen and nitrapyrin.: Investigating the seasonal application of nitrapyrin, a derivative of 2-Chloro-6-(trichloromethyl)pyridine, this study assesses its efficacy in reducing nitrate leaching and improving nitrogen use efficiency in agricultural systems (Randall and Vetsch, 2005).
- Oxidation of Nitrapyrin to 6-Chloropicolinic Acid by the Ammonia-Oxidizing Bacterium Nitrosomonas europaea.: This foundational research elucidates the microbial degradation pathway of nitrapyrin, contributing to our understanding of its environmental fate and persistence (Vannelli and Hooper, 1992).

Suspensions of Nitrosomonas europaea catalyzed the reductive dehalogenation of the commercial nitrification inhibitor nitrapyrin (2-chloro-6-trichloromethylpyridine). The product of the reaction was identified as 2-chloro-6-dichloromethylpyridine by its mass fragmentation and nuclear magnetic resonance spectra. A small amount of 2-chloro-6-dichloromethylpyridine accumulated during
