Purity vs. Actual Vial Content
Purity and quantity are related, but they are not interchangeable.
What to look for
Purity describes the proportion of detected material attributable to the target compound under a particular analytical method. Quantitative content asks how much target material is actually present.
Why it matters
A report can show very high purity while a separate quantitative assay finds more or less material than the label states. That is why our testing score rewards both measurements.
Educational material only. A COA is evidence about a tested sample and does not by itself establish regulatory approval or suitability for human use.
