Storage and in-use stability lookup
What the Institute has assessed for a compound at a given state and temperature, and what it declines to claim.
§1Lookup
§2Why so many entries say nothing is supported
An in-use period requires a stability-indicating method — one demonstrated by forced-degradation study to separate the intact compound from its degradation products — applied to the actual presentation, over the claimed period, monitoring purity, aggregate content, pH and appearance. The Institute has identified no such data for any research-supply presentation of any compound in its set.
In the absence of that, a storage recommendation is an extrapolation from formulation science. The Institute makes the extrapolation where the pharmacology is unambiguous, as with frozen storage of a dry lyophilisate, and declines it where it is not, as with any reconstituted solution. The reasoning is at CEI-MS-21 and in the in-use stability review.
