This study presents a chemical analysis-based evaluation of the herbicidal efficiency of azido-substituted triazines, with a particular focus on 2-azido-4-methylthio-6-isopropylamino-s-triazine. Triazine derivatives are well-established herbicidal agents due to their selective inhibition of photosynthesis in target weed species. The incorporation of azido and methylthio functional groups into the triazine ring is hypothesized to enhance both the biological activity and selectivity of the compound.
The synthesized compound was structurally confirmed using IR, NMR, and elemental analysis. Its herbicidal activity was tested under controlled greenhouse conditions against a panel of common broadleaf and grass weeds. Results demonstrated that 2-azido-4-methylthio-6-isopropylamino-s-triazine exhibited strong post-emergent activity, with notable inhibition of chlorophyll synthesis and plant growth at low application rates. Its physicochemical properties—such as moderate solubility, chemical stability, and compatibility with carrier solvents—further support its potential as an active ingredient in new herbicidal formulations.
This research contributes to the rational design of novel triazine-based herbicides and highlights the potential of azido-functionalized derivatives as environmentally efficient weed control agents.
