Verified Purity
Quality Assurance
Every product ships with a batch-specific Certificate of Analysis from independent third-party testing. No exceptions.
Our Quality Promise
Research integrity depends on compound purity. We verify every batch so you can trust your results.
Independent Third-Party Testing
Every batch is tested by an independent analytical laboratory — never in-house only. This eliminates conflicts of interest and ensures objective purity verification.
HPLC & Mass Spectrometry
We use high-performance liquid chromatography (HPLC) for purity analysis and mass spectrometry (MS) for identity confirmation. These are the gold-standard methods used by pharmaceutical laboratories worldwide.
≥98% Purity Standard
We hold every product to a minimum purity threshold of 98% by HPLC. Batches that fall below this standard are rejected and never shipped to researchers.
Testing Process
From synthesis to your lab — every step is documented and verified.
01
Synthesis & Purification
Peptides are synthesized via solid-phase peptide synthesis (SPPS) and purified using preparative HPLC to remove truncated sequences and impurities.
02
Independent Analytical Testing
Each purified batch is sent to an independent third-party laboratory for HPLC purity analysis and mass spectrometric identity confirmation.
03
Batch-Specific COA Issued
A unique Certificate of Analysis is generated for each production batch, documenting purity, identity, and lot number. This COA ships with your order.
What's on a Certificate of Analysis
Every COA documents the analytical results for a specific production batch. Here's what each section means.
Product Identity
Compound name, molecular formula, molecular weight, CAS number, and batch/lot number for traceability.
HPLC Purity
The percentage of the target peptide in the sample, determined by reverse-phase HPLC. Look for ≥98% on research-grade compounds.
Mass Spectrometry
Confirms the molecular identity by comparing observed mass to the expected molecular weight. A match within ±1 Da indicates correct synthesis.
Appearance & Solubility
Physical characteristics of the lyophilized powder — color, form, and reconstitution behavior in standard solvents.
Endotoxin & Sterility
Bacterial endotoxin levels (LAL test) and sterility data when applicable. Critical for in-vitro cell culture applications.
