[Lab] SWB BPC — VendorInvestigate came back 98.5% against a claimed 98.0%
Filing this under things worth writing down: SWB BPC — VendorInvestigate came back 98.5% against a claimed 98.0%. Numbers, in the order they matter: 98.5% and 98.0%. Storage guidance that names a temperature, a state and a duration reflects actual stability work. Generic guidance usually reflects a template. Stocked…
On the thin testing history in this board, and what to do about it.
Most of the compounds discussed here have a handful of independent results across the entire site, and several have none. That is a fact about how few members have paid for testing, not a judgement about the material.
What follows: buy small, test identity first for anything unusual, and post the result even when it is unremarkable. The vendor source pages are built from exactly these submissions, and the compounds with the thinnest coverage are the ones where one more entry changes the picture most. Research material is not approved for human use, so what this board can usefully build is an analytical record.
Not convinced. A purity figure without a stated method is not comparable to one that has a method attached.
Agreed — identity first for anything off the well-travelled list. The purity number is meaningless until you know what it is pure of.
identity before purity, every time, for anything unusual
Ordered under a name that turned out to cover two different molecules. Nobody’s fault but mine for not asking.
Stocked line or made to order — did they say?
That result is an area percent from an unspecified method, which is not the same as the identity confirmation being discussed.
Disagree — that name refers to at least two different molecules depending on who is selling it. The thread needs to be specific.
a mass spectrum costs little and answers the real question
Yes. Naming conventions in this corner are loose enough that the same word covers several different molecules.
