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.

- Verified purchase
Lyophilized cake was intact and fully soluble on reconstitution, with no visible particulates. Identity was consistent with the stated mass by LC-MS, and the certificate lot number matched the documentation on file.
Analytical ChemistryJun 2026 - Verified purchase
HPLC trace was consistent with the reported purity to within our instrument's tolerance. Documentation was complete and each batch was traceable to a published certificate of analysis.
Research LaboratoryJun 2026 - Verified purchase
Cold-chain packaging arrived within specification; vials were properly sealed and labeled with legible lot numbers. Turnaround from order to receipt was three business days.
Laboratory ProcurementMay 2026 - Verified purchase
Reconstitution was clean with no haze. Mass-spectrometry identity confirmation matched the target reference compound, and lot-to-lot consistency has held across repeat orders.
BiochemistryMay 2026 - Verified purchase
The certificate of analysis was available prior to purchase and matched the delivered lot on identity and purity. The reference material met our intake QC criteria without exception.
Analytical ServicesApr 2026 - Verified purchase
Vials were labeled consistently with the accompanying paperwork and net content was within the stated tolerance. Storage guidance on the certificate matched the product documentation.
