Abstract
The present study demonstrates a chemometric approach to identify the significant factors influencing the reverse phase high performance liquid chromatography (RP-HPLC) determination of metaxalone in bulk and pharmaceutical dosage forms. The combined effect of buffer pH, % organic phase and flow rate, each at three levels was screened for responses such as retention time, tailing factor and number of theoretical plates. The responses were statistically optimized with the aid of response surface methodology using Box–Behnken experimental design (BBD). Phosphate buffer (pH 5): acetonitrile (41.74: 58.26 v/v) as eluent pumped at 0.8 ml/minflow rate was found to be the optimal condition to attain desired responses. The optimized method was further validated with respect to linearity, precision, accuracy and sensitivity according to the current regulatory requirements. Finally, the developed experimental design was validated by statistical analysis using one-way ANOVA showed that the proposed method was simple, sensitive, robust and represents an improvement over the existing methods for routine analysis of the metaxalone.

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
