Verifiable purity at every step.
Aminoplex sources every compound through ISO-aligned partner laboratories with full chain-of-custody. Each lot is verified by independent third-party analytical labs before it ever reaches a research desk.
Controlled Synthesis
Solid-phase peptide synthesis under ISO-aligned protocols. Documented at every stage.
Multi-Stage Purification
Crude product purified via preparative RP-HPLC; fractions analyzed for content and impurity.
Independent Analysis
Final lot analyzed by an independent third-party laboratory: HPLC + ESI Mass Spectrometry.
Certificate of Analysis
Batch-specific COA generated with serial tracking, archived and made publicly verifiable.
How we verify identity and purity.
We rely on two complementary analytical techniques to characterize every batch — one tells us what the compound is, the other tells us how pure it is.
HPLC
- Reverse-phase chromatography
- UV detection at 210 / 220 nm
- Quantitative purity %
- Resolves trace impurities
ESI Mass Spec
- Electrospray ionization
- Confirms exact molecular weight
- Identity verification
- Detects sequence variants
≥99% Acceptance
Any lot failing the 99% chromatographic purity threshold is rejected and re-synthesized.
Batch-Specific COA
Every shipment includes the matching certificate. All COAs are archived in our public library.
Cold-Chain Handling
Lyophilized products packed with desiccant; sensitive compounds shipped with insulated containers.
