Abstract
The solubility of active pharmaceutical ingredients in various solvents is crucial to their industrial production and the development to final formulations. In this work, the solubility of rivaroxaban (form I) in the binary solvent mixtures of 1-methyl-2-pyrrolidinone with water, methanol, ethanol, and isopropanol from 273.15 to 323.15 K has been experimentally measured. Meanwhile, the dependence of the measured solubility on the temperature as well as on the composition of solvent mixtures has been simulated by Jouyban-Acree (JA) and nonrandom two liquid (NRTL) equations, respectively. The results show that as to the solubility simulation of the studied system JA and NRTL give average relative deviations of 0.1081 and 0.1064, respectively, suggesting that both JA and NRTL can act as an efficient simulation tool for the solubility of rivaroxaban (form I) in pure and mixture solvents at various temperatures.

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
