A specification is a decision and a result is a measurement. Where a template puts one in the other's field the fix is editorial, and the numbers behind it reconcile fine — 97.62 % here against the declared figure.

Specifications are decisions, results are measurements. They are not the same object.

Section 2
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.
The index specification is a threshold the index chose. A result below it is a measurement below a decision, not a regulatory status and not a safety statement. What it does establish is that this vial is not what the class specification describes.
97.52 % on L-Glutathione (reduced) is below the index specification for the class. The interesting part is the distribution: cysteinyl-glycine (−129 Da) at 1.58 % is doing most of the work, and that species is a synthesis artefact rather than a degradation product. This is a process observation about lot WXT-2605-B3833, not a storage one.
A specification is a decision and a result is a measurement. Where a template puts one in the other's field the fix is editorial, and the numbers behind it reconcile fine — 97.16 % here against the declared figure.
The index publishes the declared figure and the measured figure side by side and does not adjudicate between them. Both are on this page and the difference is stated rather than characterised.

Nothing on this record contradicts the declaration. Purity 98.19 %, largest single impurity acetylated N-terminus (+42 Da) at 0.71 %, mass balance closed.
A balance that closes says nothing about whether any of the four values is within specification. Consistency and compliance are different properties and this record demonstrates the first.
Purity 98.29 %, water 8.58 %, counter-ion 0.00 % counter-ion. Read together these say the cake is what it claims to be and the chromatographic homogeneity is the limiting property. That narrows the question usefully.
