Annotations

Signed technical comments on records. The index does not moderate annotations for agreement with its own arithmetic, and several of these disagree with it. Where a handle has made the same point on several records, one instance is shown and the rest are reachable from the records themselves.

AX-2026-042595
Purity 99.50 %, water 3.55 %, counter-ion 9.74 % TFA, mass balance closed, provenance independent. There is nothing outstanding on this record.
AX-2026-042226
A retail vial at 99.62 % is worth more evidentially than a selected vial at a higher figure. That is the whole argument for recording provenance at all.
AX-2026-041786
Where a supplier-supplied result on the same lot also exists, the pair is the informative object rather than either record alone. The batch page shows whether one does.
AX-2026-042339
Supplier-supplied provenance. Across the 300 lots in this index where both classes exist for the same lot, supplier-supplied results read a mean 0.42 pp higher (95 % CI 0.38 to 0.46). Read 99.93 % as an optimistic bound rather than a point estimate.
AX-2026-042939
Purity 99.44 %, water 3.39 %, counter-ion 5.72 % acetate, mass balance closed, provenance independent. There is nothing outstanding on this record.
AX-2026-041970
Ordering under an unremarkable name and address is the whole method. It requires no cooperation from anybody and it produces the strongest evidence this index holds.
AX-2026-042490
Purity 99.75 %, water 3.11 %, counter-ion 8.25 % acetate, mass balance closed, provenance independent. There is nothing outstanding on this record.
AX-2026-042250
Purity 98.10 %, water 5.46 %, counter-ion 6.89 % acetate, mass balance closed, provenance independent. There is nothing outstanding on this record.
AX-2026-041400
A retail vial at 99.51 % is worth more evidentially than a selected vial at a higher figure. That is the whole argument for recording provenance at all.
AX-2026-043668
A retail vial at 99.47 % is worth more evidentially than a selected vial at a higher figure. That is the whole argument for recording provenance at all.
