Documented purity
HPLC · every lotReverse-phase HPLC integrates the target peak as a share of total area; the full chromatogram is published on each lot’s Certificate of Analysis.
Why it matters: impurities introduce uncontrolled variables. A pure starting material is a prerequisite for reproducible work.
