Abstract
A Schiff base was synthesized by 3-methyl-4-amino-5-ethoxycarbonyl-methylsulfanyl-1,2,4-triazole with 3-nitrobenzaldehyde. The structure was confirmed by 1H NMR, IR, H RMS, TGA techniques and X-ray diffraction. The crystal belongs to monoclinic system, space group P21/c, with a = 8.965(2), b = 21.903(5), c = 9.197(2) A, β = 114.011(4)°, C14H15N5O4 S, Mr = 349.08, V = 1649.7(6) A3, Dc = 1.407 g·cm-3, Z = 4, F(000) = 728, μ = 0.226 mm-1, the final R = 0.0574 and wR = 0.1336 for 2932 unique reflections with I 2σ(I). Furthermore, the biological activity to four vegetable pathogens has been tested. The title compound exhibits better biological activity to four vegetable pathogens compared to the Schiff base without 5-ethoxycarbonyl and to Gibberlla saubinetti in EC95 compared with triadimefon.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
