Purity is typically reported as an area-percent value derived from an HPLC chromatogram. It compares the target peak's area to the total detected peak area under the run's parameters.
How to read a purity figure
- The value is method-dependent: different columns, gradients, and detectors can yield different figures.
- It is a relative measurement, not an absolute assay of the compound's mass.
- It does not describe residual solvents, endotoxins, or metals unless separately tested.
Purity results are informational for laboratory research. They do not indicate suitability for human use.
