Abstract
image [7790‐89‐8] ClF (MW 54.45) InChI = 1S/ClF/c1‐2 InChIKey = OMRRUNXAWXNVFW‐UHFFFAOYSA‐N (reagent used as a source of electrophilic chlorine and nucleophilic fluoride; formation of hypochlorites; synthesis of chloramines: dihalogenation of alkenes; oxidative fluorination of sulfur derivatives) Physical Data: Colorless gas at room temperature; colorless solid, mp −155.6 °C; pale yellow liquid, bp −100.1 °C; d 1.62 g cm −3 . Form Supplied in: pressurized container. Preparative Methods: gaseous chlorine monofluoride can be obtained by heating equimolar amounts of F 2 and Cl 2 at 230 °C in copper tubes, 1 or at 250 °C in nickel tubes using a 5% excess of Cl 2 . 2 Preparations involving silver salts or alkali metal fluorides upon heating have also been reported in addition with a method at low temperature using SbF 5 at 35 °C. 3 Other procedures have been described using ClF 3 with Cl 2 and CsF upon heating or with HgCl 2 at 25 °C. 4 ClF can also be prepared and used in situ by mixing N ‐chlorosuccinimide and HF. 5,6 Purification: depending on the preparative method, the major impurities are ClF 3 , HF, F 2 , and/or Cl 2 . Fractional condensation with a trap at –142 °C to retain impurities and a trap at –196 °C to condense pure ClF can be used. 4 Handling, Storage, and Precautions: chlorine fluorides are strong oxidizing agents and are toxic. Hydrolysis can produce shock‐sensitive chlorine oxides and toxic by‐products (ClO 2 F, Cl 2 , HF). ClF 3 is also a decomposition product and is highly pyrophoric. Protect from sunlight. Do not expose to temperatures above 50 °C. Keep the container closed when not in use. Reacts violently with metals and reducing agents. Appropriate shielding is required for high‐pressure work. Wear protective clothing and a face mask at all times.

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.
