Abstract
Cocrystals have been increasingly recognized as an attractive alternative for solid forms of drug products. In this work, nicotinamide (NCT) was employed as a cocrystal former with the active pharmaceutical ingredient theophylline (TP). The theophylline−nicotinamide cocrystal (hereafter TP-NCT cocrystal) was prepared by solid-state grinding and slow evaporation from ethanol, and was characterized by differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), hot-stage optical microscopy (HSM), Raman spectroscopy, and powder X-ray diffraction (PXRD) techniques. Pharmaceutically relevant properties such as powder dissolution rate, solubility and dynamic vapour sorption (DVS) of the TP-NCT cocrystal were evaluated. The results show that, the TP-NCT cocrystal, obtained in a 1:1 molar ratio of theophylline and nicotinamide, possesses unique thermal, spectroscopic, and X-ray diffraction properties. In addition, the solubility and hygroscopicity of the TP-NCT cocrystal were considerably higher than those of anhydrous theophylline.

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
