Abstract
[1191-15-7] C8H19Al (MW 142.22) (reducing agent for many functional groups; opens epoxides; hydroaluminates alkynes and alkenes) Alternate Names: DIBAL; DIBAL-H; DIBAH. Physical Data: mp −80 to −70 °C; bp 116–118 °C/1 mmHg; d 0.798 g cm−3; fp −18 °C. Solubility: sol pentane, hexane, heptane, cyclohexane, benzene, toluene, xylenes, ether, dichloromethane, THF. Form Supplied in: can be purchased as a neat liquid or as 1.0 and 1.5 M solutions in cyclohexane, CH2Cl2, heptane, hexanes, THF, and toluene. Handling, Storage, and Precautions: neat liquid is pyrophoric; solutions react very vigorously with air and with H2O, and related compounds, giving rise to fire hazards; use in a fume hood, in the absence of oxygen and moisture (see Lithium Aluminum Hydride for additional precautions); THF solutions should only be used below 70 °C, as above that temperature ether cleavage is problematic.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
