Abstract
[821-09-0] C5H10O (MW 86.13) InChI = 1S/C5H10O/c1-2-3-4-5-6/h2,6H,1,3-5H2 InChIKey = LQAVWYMTUMSFBE-UHFFFAOYSA-N (reagent used to prepare synthetic intermediates containing the 4-pentenyloxy moiety which can be activated for use as a leaving group by exposure to electrophiles) Physical Data: bp 139 °C, bp3 63 °C, bp0.45 37–39 °C; density 0.858 g cm−3; ηD25 1.4290. Solubility: 5.7% by weight in water at 25 °C,1 soluble in common organic solvents. Form Supplied in: colorless liquid; widely available. Purification: can be purified by distillation. Handling, Storage, and Precautions: keep containers tightly closed, away from heat and open flame. Store in a cool dry place. Avoid contact with eyes, skin, and clothing; avoid breathing the vapor. Wash thoroughly after handling. The toxological properties of this compound have not been thoroughly investigated.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.
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.
