Abstract
[55791-04-3] C6H16FNO5S2 (MW 265.32) InChI = 1S/C6H16NO2S.FHO3S/c1-5-7(3,6-2)10(4,8)9;1-5(2,3)4/h5-6H2,1-4H3;(H,2,3,4)/q+1;/p-1 InChIKey = VERIHBXWNIYGAA-UHFFFAOYSA-M (reagent for converting, under mild conditions, alcohols into methanesulfonate (mesylate) esters, and primary and secondary amines into methanesulfonamides1, 2) Alternate Name: easy mesyl. Physical Data: mp ∼115 °C (dec).2 Solubility: sol dry MeCN (solutions decompose over a few hours at rt).2 Form Supplied in: not commercially available. Preparative Method: reaction of MeSO2NEt2 with excess neat MeOSO2F at 50 °C for 72 h.2 Analysis of Reagent Purity: 1H NMR (CD3CN) δ: 1.40 (t, 6H), 3.11 (s, 3H), 3.60 (q, 4H), 3.70 (s, 3H).2 Handling, Storage, and Precautions: hygroscopic; hydrolyzed by moist air (products corrosive); stable indefinitely in a sealed ampoule at rt.
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.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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 source (direct Gemma or distilled Codex), not a consensus.
